formula for sin

^{-1}X + sin^{-1}Y , sin^{-1}X -sin^{-1}Ycos

^{-1}X + cos^{-1}Ycos

^{-1}X - cos^{-1}Ysummary of the last lesson

prove that :

tan [pi/4 + 1/2 cos

^{-1}a/b] + tan[pi/4 - 1/2cos^{-1}a/b] = 2b/a2.Ambani is richer than I.

Which of them is correct?

how to integratef (log(sin x ))dxwhat is integral of log(x)??????

find the value of x : sin

^{-1}x + sin^{-1}(1-x) = cos^{-1}x
