Solution by Steps
step 1
Given y=x2y = x^2, we need to find dydt\frac{dy}{dt}
step 2
To find dydt\frac{dy}{dt}, we use the chain rule: dydt=dydxdxdt\frac{dy}{dt} = \frac{dy}{dx} \cdot \frac{dx}{dt}
step 3
First, we differentiate y=x2y = x^2 with respect to xx: dydx=2x\frac{dy}{dx} = 2x
step 4
Now, we multiply by dxdt\frac{dx}{dt}: dydt=2xdxdt\frac{dy}{dt} = 2x \cdot \frac{dx}{dt}
Answer
dydt=2xdxdt\frac{dy}{dt} = 2x \cdot \frac{dx}{dt}
Key Concept
