Question

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

Answer 1

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

Answer 2

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

Answer 3

okay

Answer 4

& what about Integration of x

Answer 5

any proof of this?

Answer 6

graphical:
Integration is interpreted as the area under a curve plotted:
