Question 1034534: Write each equation in the form of an inverse function.
1. B = cos a
2. tan B = a
3. y = tan 120
4. -1/2 = cos x
5. sin 2pi/3 = square root 3/ 2
6. cos pi /3 =1/2 Answer by ikleyn(52786) (Show Source):
1. B = cos a a = arccos(B) ( + , for generality)
2. tan B = a B = arctan(a) ( + , for generality)
3. y = tan 120 120° = - arctan(y) ( think why it is so )
4. -1/2 = cos x x = arccos() ( + , for generality)
5. sin 2pi/3 = square root 3/ 2 = - arcsin() ( think why it is so ! )
6. cos pi /3 =1/2 = arccos()
