The derivatives of inverse trigonometric functions are first-order derivatives. Let us check here the derivatives of all the six inverse functions.
| Inverse Trig Function | dy/dx |
| y = sin-1(x) | 1/√(1-x2) |
| y = cos-1(x) | -1/√(1-x2) |
| y = tan-1(x) | 1/(1+x2) |
| y = cot-1(x) | -1/(1+x2) |
| y = sec-1(x) | 1/[|x|√(x2-1)] |
| y = csc-1(x) | -1/[|x|√(x2-1)] |
