`cot^(-1)3+cosec^(-1)sqrt(5)=`

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

The sum of the two angles cot^(-1) 3 and cosec^(-1) sqrt(5) is

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

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

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

The value of cot^(-1)(-1)+cosec^(-1)(-sqrt(2))+sec^(-1)(2) is

For the principal values,evaluate the following: cot^(-1)(-1)+csc^(-1)(-sqrt(2))+secs^(-1)(2)cot^(-1)(-sqrt(3))+tan^(-1)(1)sec^(-1)((2)/(sqrt(3)))
