4(cot^(-1)8+coses^(-1)sqrt(5))=pi

4(cot^(-1)3+csc^(-1)sqrt(5))=pi

4(cot ^(-1)3+"cosec"^(-1) sqrt(5))=pi

cot^(-1)9+cosec^(-1)(sqrt(41))/(4)=(pi)/(4)

Prove that 4(cot^(- 1)3+c o s e c^(- 1)sqrt(5))=pi

Prove that : (i) tan^(-1) x + cot^(-1)( x+1) = tan^(-1) (x^(2)+x+1) (ii) cot^(-1) 3 + "cosec"^(-1) sqrt(5) = pi/4

Solve for x : cot^(-1)x + sin^(-1)(1/sqrt(5)) = pi/4

Solve for x : cot^(-1)x+ sin^(-1)( 1/sqrt(5)) = pi/4

Prove that : cot^-1 3 + cosec^-1 sqrt5 = pi/4

cot(pi/2-2cot^(-1)sqrt3)

If Cot^(-1)x+Sin^(-1)(1//sqrt5)=pi//4 , then the value of x is
