This is a section about Derivative!

Derivative is a very important subject about which there is a lot to say.

For example, this sentence. And then another one.


Derivative

The code <code>f(x) + 1</code> should be <code>f(x) + 2</code>

The code `f(x) + 1` should be `f(x) + 2`

I can't believe you got such a basic fact wrong!

The derivative of a function gives its slope at a point.

More precisely, it give sthe inclination of a tangent line that passes through that point.
