Verifying an identity by using the quotient and reciprocal identities

👉 Learn how to verify trigonometric identities having rational expressions. To verify trigonometric expression means to verify that the term on the left hand side of the equality sign is equal to the term on the right hand side. To verify rational trigonometric identities with one term at the denominator, it is usually more convenient to start with getting rid of the denominator of the rational term. This can be done by multiplying both the numerator and the denominator of the rational term by the reciprocal of the denominator term.

For non-rational trigonometric identities, we can replace given trigonometric functions/identities with equivalent trigonometric functions/identities and evaluate accordingly.
