Hair Growth
1. **State the problem:** Given the rate of growth of Rapunzel's hair as $$\frac{dL}{dt} = \frac{1}{5t}$$, find the length of hair grown between the 100th day and the 200th day. 2.
Derivative Zero
1. The problem gives the function $$y = 2x^4 - x^2$$ and asks to find the value of $$x$$ for which the derivative $$y' = 0$$. 2. Find the derivative of $$y$$ with respect to $$x$$.
Rules Of Differentiation
1. **Constant Rule:** The derivative of a constant is zero. Example: If $f(x)=5$, then $f'(x)=0$.
First Derivative
1. **State the problem:** We need to find the first derivative of the function $$f(x) = x^3 - 5x + 2$$ and then evaluate it at $$x = 2$$. 2. **Find the first derivative:** Differen
Second Derivative
1. The problem is to find the second derivative of the function given as $$f(x) = 3x^3 - 2x^2 + 4x - 8$$. 2. First, find the first derivative $f'(x)$ by differentiating each term:

1. **State the problem:** Find the derivative of the function $$f(x) = \frac{x+5}{x^2-1}$$. 2. **Recall the quotient rule:** If $$f(x) = \frac{u(x)}{v(x)}$$, then $$f'(x) = \frac{u
Derivative Product
1. We are asked to find the first derivative of the function $$y = x^2 (x+1)^3$$. 2. To differentiate, we recognize this as a product of two functions: $$u = x^2$$ and $$v = (x+1)^
Multiple Integrals
1. Problem: Evaluate the integral $$\int_3^4 \frac{3x}{\sqrt{x-2}} \, dx$$ using the substitution $u = \sqrt{x-2}$. Step 1: Express $x$ in terms of $u$: $$x = u^2 + 2$$.
Integration Parts
1. The problem is to explain the integration by parts formula: $$\int_a^b u(x)v'(x)\,dx = [u(x)v(x)]_a^b - \int_a^b u'(x)v(x)\,dx.$$\n\n2. Integration by parts is derived from the
