# How do you implicitly differentiate #-y=xy-xe^-y #?

##### 2 Answers

#### Explanation:

Since, the Problem is to be solved using **Implicit Diffn.**, we will

first solve it accordingly.

By the **Product Rule** , then,

To find **Chain Rule** to get,

Hence, continuing from

**Enjoy Maths.!**

#### Explanation:

As a **Second Method** , we can solve the Problem **without** the

use of **Implicit Diffn.**

Let us rewrite the given eqn. as,

giving,

Diff.ing w.r.t. **Quotient Rule** and the **Chain Rule**,

I leave it, as an exercise, to show that our both **Answers** match!
