# Calculus For Data Science: What Do You Really Need to Know?

This one picture shows what areas of calculus and linear algebra are most useful for data scientists.

If you read any article worth its salt on the topic Math Needed for Data Science, you'll see calculus mentioned. Calculus (and it's closely related counterpart, linear algebra) has some very narrow (but very useful) applications to data science. If you have a decent algebra background (which I'm assuming you do, if you're a data scientist!) then you can learn all of the calculus you need in a few hours of study.

You don't usually need to know exactly how to take derivatives, minimize sums of squares or create clustering algorithms from scratch--there are calculators for that! But if you have a general idea of what's working in the background you'll be able to recognize when results don't make sense or what better alternatives might be available.

Very good explanation.. Really appreciate the efforts!!!

Domingo, I agree, that's a great reason and perhaps warrants a future post on "Why you would want to learn calculus".

Stephanie, I like your approach, is part of our culture of data scientist, Continue learning for improvement!

Add a reason for learning Calculus ("to recognize when results don't make sense or what better alternatives might be available")
moves your post to the next level
