To verify an identity means to ascertain that the left-hand side is equal to the right-hand side of the equality sign. To do this, we first expand all the given sum/difference of two angles trigonometric functions and then use the unit circle and the Pythagoras theorem to obtain all the known angles. We can then simplify the expressions on both sides of the equality sign to ascertain that they are equal.\n
