Calculus
Calculus is necessary if you are interested in becoming a data analyst. While it's a foundational subject, many other elements of data science also involve the use of calculus. Many machine learning algorithms require calculus. This course will teach you the basics of calculus and how it applies to machine learning models. This video will give you a few examples of how calculus can be applied to machine learning.
A course in calculus will introduce you to the fundamental ideas of probability and statistics, which you'll need to understand to analyze data. You'll be able to understand the central limit theorem. You will also learn how you can integrate multiple variables' functions and perform a range of other calculations. Finally, you will learn how optimize a function and graph the derivatives. You will also learn how to use multivariate calculus which is essential for data analytics careers.
