# What is the derivative of #pi#?

##### 1 Answer

#### Explanation:

The derivative of a constant term is always zero. Reason being, we take derivatives with respect to a variable.

We understand derivatives to be the **slope of the tangent line**, or our instantaneous rate of change. Take the following derivative:

This expression that we're taking the derivative of is in slope-intercept form (

Remember, **constant, meaning it doesn't change with respect to a variable** . It will graph as a horizontal line, just like
