What is chain rule for function $w = f(x,y)$ ? To use this rule, find the derivative of $w = xy$ w.r.t. $t$ along the path $x = \cos t$ , $y = \sin t$ . Also, find derivative of $w$ at $t = \frac{\pi}{2}$ . [1+4]

What is chain rule for function $w = f(x,y)$? To use this rule, find the derivative of $w = xy$ w.r.t. $t$ along the path $x = \cos t$, $y = \sin t$. Also, find derivative of $w$ at $t = \frac{\pi}{2}$. [1+4]

$w = f(x,y) = xy$ - $x = \cos t$ , $y = \sin t$ - Evaluate $\dfrac{dw}{dt}$ at $t = \dfrac{\pi}{2}$ --- For $w = f(x, y)$ where $x = x(t)$ and $y = y(t)$ are functions of a single variable $t$ , the chain rule gives the total derivative: $$\frac{dw}{dt} = \frac{\partial w}{\partial x}\cdot\frac{d...
