dy dx =( x/ y ) 3 + x/ y Hint: Let u= y x , dy dx =u+x du dx
Added by Ryan B.
Step 1
We are given the hint to let $u = yx$, so we can find the derivative of $u$ with respect to $x$: $$\frac{du}{dx} = y + x\frac{dy}{dx}$$ Now, substitute the given hint into the original equation: $$\frac{dy}{dx} = \frac{x}{y} (3 + \frac{x}{y})$$ Show more…
