Difference between a PDF and a CDF?

[ChemIsHard]

I'm having a lot of trouble figuring out the difference between a probability density function and a cumulative distribution function.

Is the CDF just the integral of the PDF?

Thanks in advance.

The PDF (probability density function) is the derivative of the CDF (cumulative distribution function). Conversely, the CDF is the integral of the PDF.

Alright that's what I thought. Much appreciated! I was freaking out haha.
