Trig Identities
Reciprocal, Pythagorean, & Quotient Identities
| Term | Definition |
|---|---|
| reciprocal: cscx = | 1/sinx |
| reciprocal: secx = | 1/cosx |
| reciprocal: cotx = | 1/tanx |
| quotient: tanx = | sinx/cosx |
| quotient: cotx = | cosx/sinx |
| pythagorean: (sinx)^2 + (cosx)^2 = | 1 |
| pythagorean: 1 + (tanx)^2 = | (secx)^2 |
| pythagorean: 1 + (cotx)^2 = | (cscx)^2 |
