Implicit Differentiation | Equations with Exponential and Trigonometric Functions

In this calculus tutorial/lecture video, we discuss here the implicit differentiation technique which is used in finding the derivative a function defined implicitly by an equation. In particular, we solve these two problems:
1. Find 𝑑𝑦/𝑑𝑥 if 𝑒^(𝑥/𝑦)=𝑥^2 𝑦−5.
2. Find the equation of the tangent line to the curve sin⁡(𝑥+𝑦)=𝑦^2 cos⁡𝑥 at the point (𝜋,0).
