👉 Learn how to verify trigonometric identities having rational expressions. To verify trigonometric expression means to verify that the terms on the left-hand side of the equality sign is equal to the terms on the right-hand side. To verify rational trigonometric identities, it is usually more convenient to start with getting rid of the denominator(s) of the rational term(s). This can be done by multiplying both the numerator and the denominator by the conjugate of the denominator, if the denominator involves addition/subtraction or by the reciprocal of the denominator, if the denominator involves product or the expression can be converted to Pythagoras trigonometric identity if possible.
