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

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 [-1/2,0] , find (dy)/(dx)

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

If quad cos^(-1)(2x)+2cos^(-1)sqrt(1-4x^(2)),-(1)/(2)

If 0 lt cos^(-1)x lt 1 and 1+sin(cos^(-1)x)+sin^(2)(cos^(-1)x)+sin^(3)(cos^(-1)x)+…infty=2 , then the value of 12x is
