I had already calculated the first partial derivative to equal the following:
$$\frac{\partial y}{\partial t} = \frac{\partial v}{\partial x} \frac{\partial x}{\partial t} + \frac{\partial v}{\partial t}$$
Now the second partial derivative I can use the chain rule to do and get to...
I got the first part of it down, $$L=\int_1^5 \sqrt{1+(\frac{1}{x^2})}dx$$
I just want to know if it's right to make your ##f(x)=\sqrt{1+\frac{1}{x^2}}## then compute it's second derivative and find it's max value, for the trapezoidal error formula.
I have a calculus 2 midterm coming up and given the exam review questions, this seems like this question can potentially be on it.
I've tried to look it up, but I always find the famous painters example, which I don't find satisfying.
In Calculus II, we're learning about solids of revolutions and computing their volumes.
I'm unsure when to apply the appropriate methods and how to make the correct partitions.
Please tell me if my reasoning is correct:
The disk/washer method is applied when your partitions are perpendicular...
In Calculus II, we're currently learning how to find the area of a bounded region using integration. My professor wants us to solve a problem where we're given a graph of two arbitrary functions, f(x) and g(x) and their intersection points, labeled (a,b) and (c,d) with nothing else given.

"It takes 100J of work to stretch a spring 0.5m from its equilibrium position. How much work is needed to stretch it an additional 0.75m."
Attempt: w = ⌠abF(x)dx
work = F x D
100J = F x 0.5m
F = 200J
0.75 + 0.5 = 1.25
w = ⌠0.51.25 200dx
w = 150 J
The correct answer: w = 525 J
what did I do...

x bounds: from 0 to 2
y bounds: from 0 to sqrt(2x-x^2)
After solving all that stuff I get to:
