QUESTION:

Find \(dy/dx\) and \(dy/dt\).

\(y=t x^{2}+t^{3} x\)

ANSWER:

Step 1 of 2

Given function,

\(y=t x^{2}+t^{3} x\)

Calculate the differentiation of the function y with respect to x.

Differentiating y with respect to x by taking t as a constant.

\(\begin{array}{l} \frac{d y}{d x}=t \frac{d}{d x}\left(x^{2}\right)+t^{3} \frac{d}{d x}(x) \\ \frac{d y}{d x}=(2 x) t+t^{3} \\ \frac{d y}{d x}=t\left(2 x+t^{2}\right) \end{array}\)
