`tan(sin^(-1) (4/5))`

The value of tan[sin^(-1) (3/5)+tan^(-1) (2/3)] is

sin(2tan^(-1) .(4)/(5))= ?

Prove that: sin^(-1)(-(4)/(5))=tan^(-1)(-(4)/(3))=co^(-1)(-(3)/(5))-pi

Evaluate each of the following: tan((tan^(-1)3)/(4))( ii) tan((sin^(-1)5)/(13))( iii) tan((cos^(-1)8)/(17))

Prove that sin^(-1)((4)/(5))+tan^(-1)((5)/(12))+cos^(-1)((63)/(65))=(pi)/(2)

Prove that tan^(-1) (1/4) + tan^(-1) (2/9) = 1/2 sin^(-1) (4/5)

(sin ^ (- 1) 4) / (5) + (sin ^ (- 1) 5) / (13) = (tan ^ (- 1) 63) / (16)

Evaluate the following: (i) tan{2\ tan^(-1)(1/5)-pi/4} (ii) tan(1/2\ sin^(-1)(3/4)
