    Evaluate the Integral sqrt(1+7s)ds

    Great.. So if I use that equation then I am getting-2 (6-r^3)^(1/2) + C But the book says it should be -4(6-r^3)^(1/2) +C What am i missing? (thankyou so much for the help!)

    Evaluate the Integral sqrt(1+7s)ds

    What happens when you are taking the integral of something like this... ∫\frac{6r^2}{\sqrt{6-r^3}} I tried: u = 6-r^3 du = 3r^2 but i cannot get the correct answer. Help would be great!

    Critical Points, intervals, local max/min help Calculus.

    Hey, Okay, so If I set x to equal zero, then, f'(x) equals 0. Basically I'm having problems with this whole set of problems. I'm having a hard time wrapping my head around critical points. So what you're saying is: To find a critical point: 1. find the derivative of a function...

    Critical Points, intervals, local max/min help Calculus.

    Critical Points, intervals, local max/min help! Calculus. 1. I need help with a homework problem that I just cannot get right. It asks: Answer the following questions about the functions whos derivative is given below. f'(x) = (sinx +1)(2cosx +\sqrt{3} ), 0\leqx\leq2∏ a. what are the...
