[" If "cos^(-1)((2)/(3x))+cos^(-1)((3)/(4x))=(pi)/(2)(x>(3)/(4))],[" then "x" is equal to: "]

If cos ^(-1) ((2)/( 3x )) + cos ^(-1) ((3 )/( 4x )) = pi/2 (x gt (3)/(4)) and "x" is equal to (sqrtp)/(q), then the value of (p -q) is :-

If cos^(-1)(2/(3x))+cos^(-1)(3/(4x))=(pi)/2(xgt3/4) then x is equal to

If x>0,cos^(-1)((3)/(x))=(pi)/(2)-cos^(-1)((4)/(x)) then x equals

If sin^(-1)(x-(x^2)/(2)+(x^3)/(4)-...infty)+cos^(-1)(x^2-(x^4)/(2)+(x^6)/(4)-...infty)=(pi)/(2) and 0ltxltsqrt(2) , then x is equal to

cos((3pi)/4+x)-cos((3pi)/4-x)=

Let cos^(-1)(4x^(3)-3x)=a+b cos^(-1)x If x in[-(1)/(2),-1], then a+b pi=

cos^3(x-((2pi)/3))+cos^3x+cos^3(x+((2pi)/3)))=3/4 cos3x

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