Have been given this question and am strugling abit.
Any help appreciated:
Find the work done (W) by a mechanism between the angular displacement (x) of 0 and pie/2, by intergrating the following equation:
2cos(2x) + 3sin(3x)
Thanks
Integration, cos goes to sin and sin goes to -cos.
Also, remember the chain rule for inside the brackets, differentiate the bracket and divide by what you get.
- (cancel the 2s)
- (cancel the 3s)
