જો $x = \sec \theta - \cos \theta$ અને $y = \sec^n \theta - \cos^n \theta$ હોય,તો:

$x \neq -1, y \neq -1$ માટે, જો $x = \frac{1 - \sqrt[3]{y}}{1 + \sqrt[3]{y}}$ હોય, તો $\frac{dx}{dy} =$

જો $x = a \sin 2t (1 + \cos 2t)$ અને $y = b \cos 2t (1 - \cos 2t)$ હોય,તો $\frac{dy}{dx}$ ની કિંમત શોધો.

જો $x = a(\cos \theta + \theta \sin \theta)$, $y = f(\theta)$, $f(2\pi) = 0$, $\frac{dy}{dx} = \frac{\tan \theta}{\theta}$, $\theta \neq 0$ અને $\theta \neq (2n+1)\frac{\pi}{2}$ હોય, તો $f\left(\frac{\pi}{3}\right) = $
