3. ### Find Exponential Equation from data points

Hi guys I'm helping my girlfriend with her Calc 1 homework and we seem to be stuck on this one problem. Am I missing something obvious? Homework Statement Homework Equations P = P_0 a^t \frac{5}{20} = \frac{P_0 a^1}{P_0 a^{-1}} \frac{1}{4} = a^2 a =...
4. ### Finding the net field strength due to a line of charge

I want to apologize ahead of time for my apparent inability to get LaTeX to display properly. Homework Statement λ = 3.8 x 10^(-6) C/m R = 32m r = magnitude of the hypotenuse (the book's convention, a poor choice IMHO) r = \sqrt{R^2 + x^2} k = 8.988 x 10^9 P:(0,-32) cosθ = x/r a→∞...
5. ### Evaluating a Series

Homework Statement First, I'd like to thank everybody a head of time. You guys have been an enormous help. Second, I don't mind telling you that I'm finding sequences and series extremely frustrating. I usually pick this stuff up like nobody's business. My problem is attached, but I will copy...

Homework Statement Given the following integral and value of n, approximate the integral using the methods indicated (round your answers to six decimal places): \int_0^1 e^{-3x^2} dx n = 4 (a) Trapezoidal Rule (b) Midpoint Rule This is the only one I'm having trouble...
7. ### Average Velocity and Average Speed of Integral

Homework Statement An object moves with velocity v(t) = −t2 +1 feet per second between t = 0 and t = 2. Find the average velocity and the average speed of the object between t = 0 and t = 2 Homework Equations \frac{1}{b-a} \int_a^b f'(x) dx avg value of a function The Attempt...
8. ### Volume of a boat problem

Homework Statement The design of boats is based on Archimedes' Principle, which states that the buoyant force on an object in water is equal to the weight of the water displaced. Suppose you want to build a sailboat whose hull is parabolic with cross section y=ax2, where a is a constant. Your...
9. ### Area between two graphs

Homework Statement Find the area of the region enclosed between y=4sin(x) and y=2cos(x) from x=0 to x=0.8pi. Homework Equations \int^{0.8\pi}_0 dx g(x) = 4\sin(x) f(x) = 2\cos(x) The Attempt at a Solution This problem needs to be split up into two parts...
