Pythagorean Identity
math
| Question | Answer |
|---|---|
| pythagorean identity 1 | cos^2 θ + sin^2 θ = 1 |
| pythagorean identity 2 | 1 + tan^2 θ = sec^2 θ |
| pythagorean identity 3 | cot^2 θ + 1 = csc^2 θ |
| tan θ | sin θ / cos θ |
| cot θ | cos θ / sin θ |
| csc θ | 1/sin θ |
| sec θ | 1/ cos θ |
| pythagorean identity varitation 1 | cos^2 θ = 1-sin^2 θ |
| pythagorean identity variation 2 | sin^2 θ = 1 - cos^2 θ |
| sin2 θ | 2sin θ cos θ |
| cos2 θ (#1) | cos^2-sin^2 θ |
| cos2 θ (#2) | 1- 2sin^2 θ |
| cos2 θ (#3) | 2cos^2 θ -1 |
| tan 2 θ | 2 tanθ / 1-tan^2 θ |
