WebbHere are some useful tips for proving identities: Change all trigonometric ratios to sine and cosine. Choose one side of the equation to simplify and show that it is equal to the other side. Usually it is better to choose the more complicated side to simplify. Sometimes we need to simplify both sides of the equation to show that they are equal. WebbPractice Questions on Trigonometry.
