| First side | Second side |
|---|---|
| Logb x + logb y = | Logb xy |
| Logb x - Logb y = | Logb x/y |
| n logb x = | logb x^n |
| (Logb x) / (logb a) | Loga x |
| Loge x = | Ln x |
| tan x = | (sin x)/ (cos x) |
| cot x = | (cos x)/(sinx) |
| sin(a+b) = | sin a cos b + cos a sin b |
| sin(a-b) = | Sin a cos b - cos a sin b |
| Cos (a + b) = | Cos a cos b - sin a sin b |
| Cos (a + b) = | cos a cos b + sin a sin b |
| Cos (a - b) = | cos a cos b - sin a sin b |
| P -> R : | (r, θ) -> (x, y) |
| X = | r cosθ |
| Y = | rsinθ |
| Sin x = | (1)/(cscx) |
| Cos x = | 1/secx |
| Tanx = | 1/cotx |
| cscx = | 1/sin x |
| Secx = | 1/cosx |
| Cotx = | 1/tanx |
| Sin 2x = | 2sin x cos x |
| Cos 2x = | Cos^2 x - sin^2 x 2cos^2 x -1 1-2sin^2 x |
| Cos^2 x + sin^2 x = | 1 |
| 1+ tan^2 x = | Sec^2 x |
| Cot^2 x +1 = | csc^2 x |
| R -> P : | (x. y) -> (r, θ) |
| r = | sqrt(x^2 + y^2) |
| Tanθ = | y/x (Recall: add π if x < 0) |
