sin(2 sin^(-1) sqrt(63/65)) =

sin(2"sin"^(-1)sqrt((63)/(65))) is equal to

The value of sin(1/4sin^(-1)((sqrt(63))/8)) is (a) 1/(sqrt(2)) (b) 1/(sqrt(3)) (c) 1/(2sqrt(2)) (d) 1/(3sqrt(3))

sin(1/4sin^(- 1)(sqrt 63/8)i s

sin((1)/(4)sin^(-1)((sqrt(63))/(8))is

The value of sin(1/4sin^(-1)(sqrt(63))/8) is 1/(sqrt(2)) (b) 1/(sqrt(3)) (c) 1/(2sqrt(2)) (d) 1/(3sqrt(3))

Prove that : cos^(-1).(3)/(5)+ cos^(-1).(12)/(13) = sin^(-1)((63)/(65))
