**Integral calculus**

Is Integral of f(x) w.r.t.x from 0 to a;equal to Integral of f(x-a) w.r.t.x from 0 to a?

Damon: That is a good answer which now I really understand.I thank you very much.

You have not proved to me that the Integral of lnsinx w.r.t.x from 0 to pi/2 is equal to:Integral of lnsinx w.r.t.x from 0 to pi/4 plus Integral of lncosx w.r.t.x from 0 to pi/4.

Is it the integral of lnsinx w.r.t x from 0 to pi/2 = integral lnsinx w.r.t x from 0 to pi/4 + integral lncosx w.r.t x from 0 to pi/4 ?
