Is (-sin y) = sin (-y) ? If yes why ?
Asked by jay7venture | 06 May, 2018, 04:53: PM
Expert Answer
Yes.
If we see graph of sin we can observe that sin(-y) is on the negative y-axis.
OR
If we use formula or sin (A + B) we will also get sin (-y) = -siny
sin(-y) = sin(0 - y)
= sin 0 cos(y) - cos 0 sin y
= 0 - siny
= - siny
