Find the derivative of $ sin(x^2) $ with respect to $ x $
Answer 1
To find the derivative of $ \sin(x^2) $ with respect to $ x $, we use the chain rule:
$$ \frac{d}{dx} \sin(u) = \cos(u) \cdot \frac{du}{dx} $$
Here, let $ u = x^2 $. Then:
$$ \frac{du}{dx} = \frac{d}{dx}(x^2) = 2x $$
Now apply the chain rule:
$$ \frac{d}{dx} \sin(x^2) = \cos(x^2) \cdot 2x $$
The final derivative is:
$$ \frac{d}{dx} \sin(x^2) = 2x \cos(x^2) $$
Answer 2
To find the derivative of $ \sin(x^2) $, use the chain rule:
$$ \frac{d}{dx} \sin(u) = \cos(u) \cdot \frac{du}{dx} $$
Let $ u = x^2 $, so:
$$ \frac{d}{dx} \sin(x^2) = \cos(x^2) \cdot 2x $$
