Prove: sin^(-1)(1/sqrt5)+cot^(-1)3=pi/4

Prove: sin^(-1)((1)/(sqrt(5)))+cot^(-1)3=(pi)/(4)

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

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

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

Prove that: i) sin^(-1)(1/sqrt(5))+sin^(-1)(2/sqrt(5))=pi/2

Show that sin^(-1)(1/sqrt(10))+cos^(-1)(2/sqrt5)=pi/4 .

sin^(-1)((1)/(sqrt(5)))+sin^(-1)((1)/(sqrt(10)))=(pi)/(4)

cos^(-1)""(2)/(sqrt(5))+sin ^(-1)""(1)/(sqrt(10))=(pi)/(4)

Find the principal value of each of the following: sin^(-1)((sqrt(3)+1)/(2sqrt(2)))( (ii) sin^(-1)((cos(3 pi))/(4))( iii) sin^(-1)((tan(5 pi))/(4))
