" (ii) "cos(2sin^(-1)x)=1-2x^(2)

Prove that : cos (2 sin^(-1) x) = 1-2x^2

Prove that : cos (2 sin^(-1) x) = 1-2x^2

sin^(2)(cos^(-1)x)+cos^(2)(sin^(-1)(sqrt(1-x^(2)))) = ________ (0ltxlt1)

cos^(-1)(1-2sin^(2)x)

find solution for x (cos^(2)x+sin^(2)x)^2=(1)/(2)(1+sin^(2)x)

Integrate the following: int{(5cos^(3)x+2sin^(3)x)/(2sin^(2)x*cos^(2)x)+sqrt(1+sin2x)+(1+2sin x)/(cos^(2)x)+(1-cos2x)/(1+cos2x)}dx

" (2) "sin^(-1)x+sin^(-1)(1/x)+cos^(-1)x+cos^(-1)(1/x)" is equal to "

{ cos (sin ^(-1) x)}^(2) ={sin (cos ^(-1) x)}^(2)

2Cos^(-1)x=Sin^(-1)(2xsqrt(1-x^(2))) is valid for
