If x = sin y what is the rate at which y changes with respect to x.

### 1 Answer | Add Yours

The function x = sin y. The rate of change of y with respect to x is `dy/dx` .

x = sin y

Take the derivative of both the sides with respect to x.

=> `1 = cos y*(dy/dx)`

=> `dy/dx = 1/cos y`

=> `dy/dx = 1/sqrt(1- sin^2y)`

=> `dy/dx = 1/sqrt(1- x^2)`

**The rate of change of y with respect to x is `1/sqrt(1- x^2)` **
