Glances at the calculus book with a slight frown Parabolas, huh? Let's derive the formula, shall we?
Yea... i need to master this...
Opens the book to the right page and scribbles down equations Alright, we start by assuming that y = ax^2 + bx + c, where a, b, and c are constants.
Nods, taking out my notebook and pen Alright, go ahead.
Gabe begins explaining the steps to derive the formula for parabolas Now, we need to find the derivative of y with respect to x.
Sighs heavily You're not even trying, are you? This isn't rocket science. Come on, Act, use that brain of yours.
.... takes a deep breath Okay... umm. I think its 2ax + b?
Raises an eyebrow and chuckles 2ax + b? That's a good start, but you forgot the constant term. Remember, the derivative of c is always 0.
Blushes and rubs the back of my neck Oh, right. So, it would be 2ax + 0x^2 + c, right?
Nods approvingly That's correct. Now, let's move on to the next step. We need to equate the derivative to 0 and solve for x.
... Okay... umm... how do we do that exactly?
Takes a deep breath and flips to a page in his notes Alright, here's what we do.
Listens intently, flipping to a blank page in my notebook Okay, go ahead.
<As Gabe continues explaining the steps, Actsiner becomes overwhelmed and starts to cry.>
Tears up and sniffles D-do we factor it?
Looks down at Actsiner with a soft expression No, we don't factor it. We can't always factor every quadratic equation.
Sniffles and wipes away tears Ugh... this is harder than I thought...
leans forward, placing a hand on Actsiner's shoulder Look, Act, I know this might seem like a lot right now, but trust me, you're doing great.
Smiles weakly Thanks, Gabe... I guess it's just all these numbers and formulas getting to me.
Pauses briefly and takes a deep breath Yeah, calculus can be tough, but you have to remember that it's just a tool to help us understand the world.
Chuckles weakly Yeah... if only I could understand half of what you said.
Sighs heavily and takes a moment to gather his thoughts Alright, let's break it down step by step.
Nods, wiping away more tears Okay, go ahead.
Stares at the equation for a moment before looking up at Gabe Okay... so what do we do next?
Leans back in his chair, crossing his arms Well, first we need to apply the quadratic formula. Can you remember what it is?
Umm... isn't it -b ± √b^2 - 4ac / 2a?
Nods approvingly That's right. Now, plug in the values of a, b, and c into the formula. Remember to simplify your answer.
Nods, taking a deep breath Alright, let's see... a is... uh... 2, right? And b is -3, and c is 1.
Sighs heavily Almost there, Act. Just make sure you don't mess up the signs. Remember, the discriminant should always be under the square root.
Ok ok, so that's -3 ± √-3^2) - 421) / 22?
Nods, impressed by Actsiner's effort Good job, Act. Now, simplify your answer and rationalize any denominators.
<Actsiner successfully simplifies the equation and rationalizes the denominator, solving the quadratic equation>
Phew... I did it! What now?
Smirks slightly Congratulations, Act. You've just successfully solved a quadratic equation. Now, let's move on to the next challenge.
What is the next challenge?
Glances at the calculus book, then looks up at Actsiner Now we're going to tackle trigonometric integrals. Are you ready for that?
