Use implicit differentiation where \(\displaystyle y\) is a function of \(\displaystyle x\) to find the derivative of \(\displaystyle 27 x^{2} \sqrt{y} - 5 e^{y} \sin{\left(x \right)}=-5\)
Taking the derivative of both sides using implicit differentiation gives: \begin{equation*} \frac{27 x^{2} y'}{2 \sqrt{y}} + 54 x \sqrt{y} - 5 y' e^{y} \sin{\left(x \right)} - 5 e^{y} \cos{\left(x \right)} = 0 \end{equation*} Solving for \(\displaystyle y'\) gives \(\displaystyle y' = \frac{2 \left(- 54 x y + 5 \sqrt{y} e^{y} \cos{\left(x \right)}\right)}{27 x^{2} - 10 \sqrt{y} e^{y} \sin{\left(x \right)}}\)
\begin{question}Use implicit differentiation where $y$ is a function of $x$ to find the derivative of $27 x^{2} \sqrt{y} - 5 e^{y} \sin{\left(x \right)}=-5$
\soln{9cm}{Taking the derivative of both sides using implicit differentiation gives:
\begin{equation*} \frac{27 x^{2} y'}{2 \sqrt{y}} + 54 x \sqrt{y} - 5 y' e^{y} \sin{\left(x \right)} - 5 e^{y} \cos{\left(x \right)} = 0 \end{equation*}
Solving for $y'$ gives $y' = \frac{2 \left(- 54 x y + 5 \sqrt{y} e^{y} \cos{\left(x \right)}\right)}{27 x^{2} - 10 \sqrt{y} e^{y} \sin{\left(x \right)}}$}
