" (iii) "cos^(-1)(2x)/(5)

Solve for x, if : tan (cos^(-1)x)=(2)/(sqrt(5))

Find the domain of defination the following functions. f(x)=sqrt(3-x)+cos^(-1) ((3-2x)/(5))+ln (2|x|-3)

if (3sin^(-1)x+pix-pi)^(2)+{sin(cos^(-1)((x)/(5)))}^(2)-2sin(cos^(-1)((x)/(5)))=-1 then which of the following is/are Correct?

if (3sin^(-1)x+pix-pi)^(2)+{sin(cos^(-1)((x)/(5)))}^(2)-2sin(cos^(-1)((x)/(5)))=-1 then which of the following is/are Correct?

Find the domain of the real-valued functions: f(x)=sqrt(3-x)+cos^-(1)((3-2x)/5)

Domain of the function f(x) = sqrt(3-x) + cos^(-1)((3-2x))/5 is

cos^(-1) ""(5)/(x)+cos^(-1) ""(12)/(x)=(pi)/(2)

If (sin^(-1) x)^2 + (cos^(-1)x)^2 =(5pi^2)/8 then one of the values of x is
