The equation of normal to the curve x^(2...

The equation of normal to the curve `x^(2) + y^(2) = r^(2)` at `p (theta)` is

A

`x sin theta - y cos theta = 0`

B

`x sin theta + y cos theta = 0`

C

`x cos theta - y sin theta = 0`

D

`x cos theta + y sin theta = 0`

Text Solution

Verified by Experts

The correct Answer is:
A
Equation of normal is `(x)/(cos theta) = (y) /(sin theta)`
`implies x sin theta - y cos theta = 0`
