Proving Trigonometric Identities
| Given function, f(x) = |
Given another function, g(x)= |
|---|---|
| sin(2x) = | 2sin(x)cos(x) |
| sin(x)/cos(x) = | tan(x) |
| cos(2x) = | 1-2sin2(x) |
| cos2(x) + sin2(x) = | 1 |
| (1-cos(2x)) / (1-sin2(x)) = | 2Tan2(x) |
| tan(x)cot(x)-sin2(x) = | cos2(x) |
| cot(2x) = | (cot2(x)-1) / (2cot(x)) |
| cos(x)/(1-sin(x) = | sec(x) + tan(x) |
