<ul><li><p>Trigonometric IdentitiesPutting the Puzzle Pieces Together</p></li><li><p>Establishing IdentitiesTwo functions f and g are said to be identically equal if f(x) = g(x) for every value of x for which both functions are defined. Such an equation is referred to as an identity.</p></li><li><p>Establishing an IdentityUse the basic trig identities to establish the identitycsc tan = sec </p></li><li><p>Guidelines for Establishing IdentityStart with the side containing the more complicated expressionRewrite sums or differences of quotients as a single quotientSometimes, rewriting one side in terms of sines and cosines only will helpAlways keep your goal in mind. Keep looking at the other side of the equation as you work</p></li><li><p>Establishing an IdentityEstablish the identity</p></li><li><p>Guidelines for Establishing IdentitiesBe careful not to handle like an equation. You cannot establish an identity by such methods as adding the same expression to each side and obtaining a true statement. </p></li><li><p>Establishing an IdentityEstablish the identity</p></li><li><p>Establishing an IdentityEstablish the identity</p></li><li><p>Solution</p></li><li><p>Establishing an IdentityEstablish the identity</p></li><li><p>Solution</p></li><li><p>Establishing an IdentityEstablish the identity</p></li><li><p>Solution</p></li><li><p>Establishing Inverse Trig Identities</p></li><li><p>Establishing Trig IdentitiesMany more examples on pgs. 478 479</p><p>On-line examples</p></li><li><p>Solution</p></li><li><p>Establishing Inverse Trig IdentitiesShow that</p></li><li><p>Solution</p></li><li><p>One Last ToughieEstablish the identity</p></li></ul>
