Identity theft is a rising crime. Every year more than 60 million Americans are affected by identity theft, according to an online survey by The Harris Poll carried out in 2018.

### 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.

Even if we commit the other useful identities to memory, these three will help be sure that our signs are
We can’t just integrate cos^2 (x) as it is, so we want to change it into another form, which we can easily do using trig identities. Integral of cos^2 (2x) Recall the double angle formula: cos (2x) = cos^2 (x) – sin^2 (x). Expand cos(2x)^2. Use the double-angle identity to transform to .

### which can be rearranged to yield the identity cosAcosB = 1 2 cos(A−B)+ 1 2 cos(A+B). (10) Suppose we wanted an identity involving sinAsinB. We can ﬁnd one by slightly modi-fying the last thing we did. Rather than adding equations (3) and (8), all we need to do is subtract equation (3) from equation (8): cos(A−B) = cosAcosB +sinAsinB
