but i still did not get sin x - 1/3 sin^3 (x)+c... bcoz the question ask to prove..

ok the i get integration of (cos x - u^2) du.. how to solve integration of cos x in term of u?

but how to solve the integration of cos x-u^2 du?

\[\cos(x-u^2) du\]

is this ur question ?

no.. like this integration of (cos x)-(u^2) du

yes but how ti integrate cos x in term of du?

use the substitution method.

ok i get it now.. thank u..sorry i was too slow..

\[\cos^2x*cosx dx=\cos^3x \]

U r wlcme :) ... np!
