Derivative Exponential Csc A815Ac
1. **State the problem:** Find the derivative $y'$ if $y = -e^{\csc(x^2)}$.
2. **Recall the chain rule:** If $y = f(g(x))$, then $y' = f'(g(x)) \cdot g'(x)$.
3. **Identify the outer and inner functions:**
- Outer function: $f(u) = -e^u$ where $u = \csc(x^2)$.
- Inner function: $u = \csc(x^2)$.
4. **Differentiate the outer function:**
$$f'(u) = -e^u$$
5. **Differentiate the inner function $u = \csc(x^2)$:**
Recall that $\frac{d}{dx} \csc(v) = -\csc(v) \cot(v) \cdot v'$.
Here, $v = x^2$, so $v' = 2x$.
Therefore,
$$u' = -\csc(x^2) \cot(x^2) \cdot 2x$$
6. **Apply the chain rule:**
$$y' = f'(u) \cdot u' = -e^{\csc(x^2)} \cdot \left(-\csc(x^2) \cot(x^2) \cdot 2x\right)$$
7. **Simplify:**
$$y' = 2x e^{\csc(x^2)} \csc(x^2) \cot(x^2)$$
**Final answer:**
$$y' = 2x e^{\csc(x^2)} \csc(x^2) \cot(x^2)$$
