Logically mathematical identities are tautologies that is they are expressions which restate the same expression in a different way In other words the identities allow you to restate a trig 1 Trigonometric Identities you must remember The big three trigonometric identities are sin2 t cos2 t 1 sin A B sin A cos B cos A sin B we can derive many other identities Even if
The square of cosine function equals to the subtraction of square of sin function from one is called the cosine squared formula It is also called as the square of cos function identity There are many different ways to prove an identity Here are some guidelines in case you get stuck 1 Work on the side that is more complicated
