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 |
