Cos x can be written in terms of Sine using the identity Cos x = Sin (90 - x)

• Use the identity Cos x = Sin (90 - x)

• Substitute x with the given angle in degrees or radians

• Simplify the expression if poss...read more

To express sin x + cox x in terms of sine function

Let us start with the trigonometric identity

sin2x + cos2x = 1

cos x = ±√1-sin2X

sin x + cos x= sin x ±√1-sin2x

Using complement / cofunction identit...read more
