Do you perhaps mean "identities"...? Because there are infinitely-many "equations". :shock:

Try Googling "trig identities". Make sure you know the squaring equivalencies, the double- and half-angle identities, and the angle-sum and -difference identities. There are others, but those generally get the job done. :wink:
