Likewise, we can use the fact that to find a half angle identity for sine.
As long as the substitutions are correct, the answer will be the same.
We have seen that algebra is very important in verifying trigonometric identities, but it is just as critical in simplifying trigonometric expressions before solving.
Basic properties and formulas of algebra, such as the difference of squares formula and the perfect squares formula, will simplify the work involved with trigonometric expressions and equations.
We already know that all of the trigonometric functions are related because they all are defined in terms of the unit circle.
