Calculus
Calculus is an essential skill for anyone who wants to become a data analyst. Calculus is an essential subject in data science. But it's not the only one. Many algorithms in machine learning require calculus. This course will introduce you to calculus and show how it can be applied to machine learning models. This video will show you how to use calculus in machine-learning.
A course in calculus introduces you to the concepts of probability & statistics that you will need to be able to analyze data. The central limit theorem, as well as probability distributions, will be covered. You'll also learn how to integrate functions of several variables, as well as perform a variety of other calculations. Ultimately, you'll learn how to optimize a function and graph its derivatives. You will also learn how to use multivariate calculus which is essential for data analytics careers.
