210 HAND-IN HOMEWORK WI 3. Prove the trigonometric identity: 1 + sinx + cos. + CSX - sinx (Keep in mind that you can't merely mutliply both sides by 1 + com would be assuming the truth of the identity to prove it) secx + tanx ely mutliply both sides by 1 + cos x - sinx, since then you e identity to prove it)
