So it is easier to look up say sec ( x) values than calculate 1 cos ( x) in order to get the same answer.

WebTrig identities Trigonometric identities are equations that are used to describe the many relationships that exist between the trigonometric functions. Among other uses, they can be helpful for simplifying trigonometric expressionsand equations. The following shows some of the identities you may encounter in your study of trigonometry. WebMostly trig is just using all the old formulas and identities you know and reapplying them. However there might still be some base formulas which you would need to remember such as the summation formulas for trig functions eg. sin (a+b).
