HOW TO SOLVE TRIGONOMETRIC IDENTITIES USING T FORMULA TRICK
Today we will be solving trigonometric identities using t formula trick! Make sure to stick to the end to see what are the t formula and how you can apply it to solve trigonometric identities!
The t formula are based on double angle results. When it comes to solving trigonometric identities using t formula you can best apply it when the proof involves double angles. This method for solving trigonometric identities is better than using the other identities as there is a nice trick we can use to make the proofs easier.
Basically solving trigonometric identities using t formula reduces a trig proof to an algebraic proof, which is generally easier for most people.
