Ok this I just cannot work with. Does anyone have any tips/hints on how to integrate trig functions?

Would really appreciate the working to any of these questions... I have such trouble with trig. 1. Given d2y/dx2 = 9sin3x, find y if there is a stat pt at (pi/2, 1) [how do you get to y from its double derivative?] 2. Find lim as x->0 : 1 - cos(2x)/x(squared) [how do you work with x when...

Thanks. :)

Find the volume of the solid formed when the line x + 3y - 1 = 0 is rotated about the x-axis from x = 0 to x = 8. Also - The area bound by the curve y = x^2 and the line y = x + 2 is rotated about the x axis. Find the exact volume of the solid formed. I've been staring at volumes...
