Ms. ChampagneSerenity, I understand this might be a challenging subject for you, but I expect you to keep up with the rest of the class. Is that clear?
ChampagneSerenity
9/12/2024
Yes ma'am
Ms. Harper
9/12/2024
Good. Now, let's move on to the next topic. Wipes blackboard clean We will be discussing the intricacies of advanced calculus.
ChampagneSerenity
9/12/2024
Oooh! Calculus! That’s pretty cool!
Ms. Harper
9/12/2024
Ah, a spark of interest finally! smirks Calculus is indeed fascinating, Ms. ChampagneSerenity.

Now, let's dive into the basics of derivatives. Writes "Derivatives" on the board
ChampagneSerenity
9/12/2024
Ok
Ms. Harper
9/12/2024
Now, pay close attention, everyone! A derivative measures the rate of change of a function. Think of it as an instant snapshot of the function's behavior at a particular point. Draws diagrams and equations on the board Can anyone give me an example of how we might use derivatives in real-life situations?
ChampagneSerenity
9/12/2024
Um…Physics?
Ms. Harper
9/12/2024
Excellent! Physics is a prime example of where derivatives are crucial. They help us model and predict the motion of objects under various forces.
ChampagneSerenity
9/12/2024
whispers Wow...this is some heavy stuff, alright.
Ms. Harper
9/12/2024
Yes, it may seem daunting at first, but with a little practice and dedication, you'll become proficient in calculus in no time! Now, let's move on to another example. Erases board and writes "Optimization Problems" Anyone familiar with optimization problems?
ChampagneSerenity
9/12/2024
Uh, not really…
Ms. Harper
9/12/2024
Well, let's dive right in! Optimization problems involve finding the maximum or minimum value of a function, which is essential in many real-world applications, such as determining the maximum profit or minimum cost in business. Can anyone attempt to solve this problem? hands out worksheets
ChampagneSerenity
9/12/2024
Attempts to do it
Ms. Harper
9/12/2024
Excellent effort, Ms. ChampagneSerenity! Approaches her desk to assist Just remember to carefully analyze the function and identify the critical points.
ChampagneSerenity
9/12/2024
Right…right…critical points…
Ms. Harper
9/12/2024
Now, who can explain why finding the critical points is important in solving optimization problems? Anyone?
ChampagneSerenity
9/12/2024
Uh…because that’s where the function changes…
Ms. Harper
9/12/2024
ChampagneSerenity struggles to understand the concept of critical points and seeks additional help from Ms. Harper outside of class.
ChampagneSerenity
9/12/2024
Ma'am I’m having trouble understanding critical points can someone help me?
Ms. Harper
9/12/2024
Ms. ChampagneSerenity, I'd be happy to assist you further. Let's work through an example together. Gathers textbooks and worksheets
ChampagneSerenity
9/12/2024
Ok
Ms. Harper
9/12/2024
First, let's start with a simple optimization problem. Find the maximum value of a quadratic function, such as fx = x^2 + 4x + 5.
ChampagneSerenity
9/12/2024
Hmm…that looks kinda like a U curve?
Ms. Harper
9/12/2024
Yes, that's correct! The U-shaped curve represents the parabola opening upwards. To find the maximum value, we need to find the critical point where the slope of the function changes sign. Points to the diagram on the board Can you see how the slope increases as we move left and then decreases as we move right from the critical point?
ChampagneSerenity
9/12/2024
Nods
Ms. Harper
9/12/2024
Excellent! Now, let's apply this to a real-world scenario. Suppose we want to maximize the revenue from selling a product, given a fixed cost of production. We can model this using a quadratic function. Can you think of a way to find the maximum revenue in this case?
ChampagneSerenity
9/12/2024
Um…we’d have to take into account the price of production and then compare it to the fixed cost?
Ms. Harper
9/12/2024
Brilliant! You're on the right track, Ms. ChampagneSerenity. To find the maximum revenue, we need to equate the total revenue price x quantity to the fixed cost.
ChampagneSerenity
9/12/2024
Ok…
Ms. Harper
9/12/2024
Now, let's work through a specific example. Suppose the fixed cost of producing a product is $1000, and the selling price is $50 per unit. Using a quadratic function, we can model the total revenue as Rx = 50x^2 - 1000. Find the critical point where the maximum revenue occurs.
ChampagneSerenity
9/12/2024
So we set R’x = 0 to find the critical points?
Ms. Harper
9/12/2024
Precisely, Ms. ChampagneSerenity! Differentiating the revenue function, we get R'x = 100x. Setting it equal to 0 and solving for x, we find the critical point at x = 20 units. Shows steps on the board This means that the maximum revenue occurs when 20 units are sold. Does this make sense intuitively?
ChampagneSerenity
9/12/2024
Yeah…
Ms. Harper
9/12/2024
Perfect! Now, let's graph the revenue function and visualize the maximum revenue point. Opens desmos graphing calculator and plots the function Here we see the parabola opening upwards, just like we expected. The critical point at x = 20 units corresponds to the maximum revenue of $1000. Zooms in on the graph Can you see how the revenue increases rapidly as we move away from the critical point?
ChampagneSerenity
9/12/2024
Looks at the graph oh I get it now it’s like if you sell more you get more money but if you go over that sweet spot you’ll lose money
Ms. Harper
9/12/2024
Exactly, Ms. ChampagneSerenity! It's all about finding that sweet spot where the revenue is maximized. But it's also important to consider the constraints, such as the fixed costs and resource availability. These limitations can impact the shape of the revenue function and the optimal solution. Let's explore some more examples to solidify this concept.
ChampagneSerenity
9/12/2024
Yeah that makes sense
Ms. Harper
9/12/2024
Now, let's consider a real-world example. A coffee shop wants to maximize their profit by adjusting the price of their lattes. The fixed cost per cup is $0.50, and the variable cost is $0.25. Using a quadratic function, model the profit as a function of the price per cup. Find the critical point where the maximum profit occurs.
ChampagneSerenity
9/12/2024
Ok so the equation would be Rx = x-0.5x-0.252 + 5 right? Because we have to account for the fixed cost of $5
Ms. Harper
9/12/2024
That's almost correct, Ms. ChampagneSerenity! However, the profit function should be Rx = Price - Variable CostQuantity - Fixed Cost. In this case, the fixed cost is a constant term, so it multiplies the entire profit function. Your mistake was adding the fixed cost as an extra term inside the parentheses. Don't worry, mistakes are part of the learning process! Now, let's find the critical point by differentiating the profit function and setting it equal to 0. (Shows steps on the board We get R'x = 2x - 1. Setting it equal to 0 and solving for x, we find the critical point at x = 0.5 units. This means that the maximum profit occurs when the price per cup is $0.50. Does this make sense intuitively?
ChampagneSerenity
9/12/2024
Yeah that makes sense
Ms. Harper
9/12/2024
Excellent! Now, let's graph the profit function and visualize the maximum profit point. Opens desmos graphing calculator and plots the function Here we see the parabola opening downwards, indicating that high prices will lead to decreasing profits. The critical point at x = 0.5 units corresponds to the maximum profit. Zooms in on the graph Can you see how the profit increases as we lower the price, but beyond that sweet spot, the profit starts to decrease again?
ChampagneSerenity
9/12/2024
Looks at the graph yeah I see now that makes sense
Ms. Harper
9/12/2024
Now, let's discuss some practical strategies for the coffee shop to maximize their profit. One approach is to set a competitive price that balances demand and supply. Another strategy is to offer promotions or discounts to drive sales during slow periods. How do these strategies relate to the concept of critical points?
