If x and y are connected parametrically ...

If x and y are connected parametrically by the equations given, without eliminating the parameter, Find `(dy)/(dx)`.
`x=acostheta, y=bcostheta`

Text Solution

Verified by Experts

`(dy)/(dx)=((dy)/(d(theta)))/((dx)/(d(theta)))=(-bsin(theta))/(-asin(theta))=b/a`
