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...

I've been looking at questions that ask me to explain HOW approaches to history have changed over time, and I realise I don't know how to structure a proper answer - how to best put all my information into an argument. Any suggestions?
