Integration by Parts is a special method of integration that is often useful when two functions are multiplied together, but is also helpful in other ways. ∫uv=u∫vdx−∫u′(∫vdx)dx Answer and Explanation: Assume I=∫0π2si...
I need to know how to integrate this function: sin(sqrt(x)) I did this: u = sqrt(x) du/dx = 1/(2sqrt(x)) S(sin(sqrt(x))dx) = S(sin(u)*dx*du/dx/(2sqrt(x)) = S(Sin(u)/u du) But then I got stuck: integration by parts won't work, trig substitution is out......
Integrating trig powers, why not by parts? Homework Statement Please help me understand the reason for substituting various trig identities into trig functions with powers instead of integration by parts. Does integration by parts not work on trig functions with powers, or is it just so much work...
