In order to prove the trigonometric identity, we need to start with one side and use known identities to get to the other side: LS={1-sinx}/cosx multiply by 1+sinx in numerator and denominator Verify the Identity sec(x)-tan(x)sin(x)=cos(x) Start on the left side. Because the two sides have been shown to be equivalent, the equation is an identity. find an identity for sinx; find an identity for tanx. Then put it in a form where you are not "stacking fractions." use your new "definitions" to confirm that cos 2 x + sin 2 x = 1 and tan 2 x + 1 = sec 2 x; check that your definitions are consistent with cos2x = cos 2 x - sin 2 x and two other identities of your choice. Verify the Identity cos(x)tan(x)=sin(x) Start on the left side.
