$$\phi = \sin^{-1} 3/5$$

anonymous · Answer

dont you mean inverse sin 3/4?

anonymous · Answer

if let a be any angle and b be any number which belongs to the set {-1,1} as sin value doesn't exceed 1 and -1.... hence principle value of a lies from {-pi/2,pi2} .........if b=sin a the inverse of sin b = a

@jim92 sorry but it would be inverse sin3/5 and inverse tan3/4
