I'm having trouble integrating this by parts. So far I have h(x) = -60cos((PI/2.623)x)+100 - 8 ...... and p(x) = x, with my limits of integration being 0 to 0.2. Could someone please work this out for me and explain it?
I am trying to integrate this function... the answer I found was through the use of a calulator. . It's 2pi times the integral from 0 to .2 of x times -60cos of pi/2.623 x +92
Well for starters, integrating the 42 should be easy enough. As for the rest, try letting u = x (since differentiating turns it into a constant value) and dv = the cosine stuff.
