Express in terms of : cos^(-1)(2x^(2)-1) to cos^(-1)x for -1lexlt0

If x in [-1, 0) then find the value of cos^(-1) (2x^(2) -1) -2 sin^(-1) x

If x in [1, 0) , then find the value of cos^(-1) (2x^(2) - 1) - 2 sin^(-1) x

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

cot {tan ^ (- 1) x + tan ^ (- 1) ((1) / (x))} + cos ^ (- 1) (1-2x ^ (2)) + cos ^ (- 1) ( 2x ^ (2) -1) = pi, x> 0

Prove that cos^(-1){(1+x)/(2)}=(cos^(-1)x)/(2)

cos^(-1){1/2x^(2)+sqrt(1-x^(2))sqrt(1-(x^(2))/(4))}=cos^(-1)((x)/(2))-cos^(-1)x holds for what values of x?

If y=cos^(-1)(2x)+2cos^(-1)sqrt(1-4x^2),\ \ \ x \ \ is \ [0,1/2] , find (dy)/(dx) .

If y=cos^(-1)(2x)+2cos^(-1)sqrt(1-4x^2), 0
