If all else fails turn everything into sine x and cosine x and see what happens! Usually there is lots of algebra between using the trig functions.

Sec 4.2 – Trigonometric Identities. Sum & Difference Identities. Name: Consider the diagram at the right of a unit circle. 1. First determine the coordinates
Other trignometric identities reflect a much less obvious property of the cosine and sine functions their behavior under addition of angles. This is given.

In this unit we are going to look at trigonometric identities and how to use them to solve trigono- metric equations. A trigonometric equation is an
Some trigonometric identities follow immediately from this definition in particular
native forms. To do this we use formulas known as trigonometric identities. A number of commonly used identities are listed here: 1. The identities. tanA =.
know the identities associated with sin2 ? + cos2 ? = 1. • know the expressions for sin
Some integrals involving trigonometric functions can be evaluated by using the trigonometric identities. These allow the integrand to be written in an
The formulas or trigonometric identities introduced in this lesson constitute an integral part of the study and applications of trigonometry.
Some trigonometric identities follow immediately from this definition in particular
reciprocal identities. As we mentioned above the eight basic identities are all derived from the definition of the six trigonometric functions. To derive the
The “big three” trigonometric identities are sin2 t + cos2 t = 1. (1) sin(A + B) = sinAcosB + cosAsinB. (2) cos(A + B) = cosAcosB ? sinAsinB.
