As we know that Integration of Sinx is -cosx & integration of cosx is Sinx can any one tell me the proof of above results

OpenStudy (anonymous):

use the series expansion of sin(x) and cos(x).. it reduces to algebraic functions integrations.Assume you have ust started learning integration. Good question, Cheers! :D

OpenStudy (anonymous):

sin(x) = x -x^3/3! + x^5/5! -x^7/7! +....

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

& what about Integration of x

OpenStudy (anonymous):

any proof of this?
