cos^(-1)x sqrt(3)+cos^(-1)x=(pi)/(2)

Prove that cos^(-1)(x)+ cos^(-1){(x)/(2)+sqrt(3-3x^(2))/(2)}=(pi)/(3) .

Evaluate cos [(pi)/(6) + cos^(-1) (-(sqrt(3))/(2))]

cos{cos^(- 1)((-sqrt(3))/2)+pi/6}

The sum of solutions of the equation 2 sin^(-1) sqrt(x^(2)+x+1)+cos^(-1) sqrt(x^(2)+x)=(3pi)/(2) is :

The number of solutions for the equation 2 sin^(-1)(sqrt(x^(2) - x + 1)) + cos^(-1)(sqrt(x^(2) - x) )= (3pi)/(2) is

Prove that : "cos"^(-1)sqrt((2)/(3))-"cos"^(-1)(sqrt(6)+1)/(2sqrt(3))=(pi)/(6)

The sum of the solutions of the equation 2sin^(-1)sqrt(x^(2)+x+1)+cos^(-1)sqrt(x^(2)+x)=(3pi)/2 is

cos {cos ^ (- 1) ((- sqrt (3)) / (2)) + (pi) / (6)}
