## Why do CS majors need math?

Computer science students obviously need to use mathematics because it encourages logical reasoning, critical thinking, abstract thinking, problem-solving as well as creativity which has a positive effect on their learning of their courses in Computer Science. …

**Do you need to know linear algebra for computer science?**

Linear algebra provides concepts that are crucial to many areas of computer science, including graphics, image processing, cryptography, machine learning, computer vision, optimization, graph algorithms, quantum computation, computational biology, information retrieval and web search.

**Why do CS majors need calculus?**

The reason Calculus is a prerequisite to CS is because it filters out “unwanted” students, mainly those who have weak problem solving or critical thinking skills, and students who put minimal effort into their work. While CS does not utilize calculus, it does require the skills that allow calculus students to succeed.

### What is linear algebra a prerequisite for?

The pathways to advanced mathematics courses all begin with linear algebra and multivariable calculus, and the standard prerequisite for most linear algebra and multivariable calculus courses includes two semesters of calculus.

**Is CS a lot of math?**

Also, studying Computer Science or Computer Engineering involves a lot of math, but this is not really necessary on the field. 90\% of a CS degree involves studying things that are really interesting, sure, but hardly practical. There’s certainly a good amount of programming jobs that require math.

**What does linear algebra cover?**

Linear algebra is the study of lines and planes, vector spaces and mappings that are required for linear transforms. It is a relatively young field of study, having initially been formalized in the 1800s in order to find unknowns in systems of linear equations.

#### Why linear algebra is important in data science?

Linear algebra is the most important math skill in machine learning. Most machine learning models can be expressed in matrix form. A dataset itself is often represented as a matrix. Linear algebra is used in data preprocessing, data transformation, and model evaluation.

**Can I skip linear algebra?**

So, can a machine learning enthusiast skip linear algebra and flourish? The short answer is — NO.

**Is calculus a prerequisite for computer science?**

Requirements vary across programs, but many require students to take three semesters of calculus. Calculus is an advanced mathematics course that teaches students about rates of change and it is essential to the study of computer science.

## Should CS majors take Calc 3?

You probably won’t use the subects in calc 3 in CS, but you should still take it for sure. You should take it, but it will not be used at all in most of your courses, unless you take a course in computer graphics and/or computer vision. You really should concentrate on discrete maths more.

**Why do you need linear algebra for data science?**

Linear Algebra is a branch of mathematics that is extremely useful in data science and machine learning. Linear algebra is the most important math skill in machine learning. Linear algebra is used in data preprocessing, data transformation, and model evaluation.

**How is linear algebra different from algebra?**

Algebra is almost (as mentioned by Steve) confused as being fancy arithmetic. However, algebra just refers to manipulations of more abstract entities. Linear algebra refers to algebraic manipulation of straight lines, vectors, scalars, system of linear equations, and matrices (Basics).

### What are the most important prerequisites for a CS graduate?

Familiarity with vector calculus, partial derivatives, etc., is essential for this reason. Second, with the explosion in big data we need future CS grads to understand data science fundamentals — including a deeper appreciation of probability and statistics than before, which invariably means more calculus.

**Do computer science majors have to learn calculus?**

Most CS programs started within either Mathematics or Electrical Engineering programs. Both of those fields legitimately require calculus. I went to MIT, where CS was added to the EE department. All CS majors were required to learn both digital and analog electronics, the latter of which requires calculus.

**Why are there so many math classes in Computer Science?**

The exact nature and number of math classes required in a CS program may in part be driven by departmental tradition. For example, in the school I attended, the CS program had grown out of the math program in the early 1970s. Therefore, math was heavily emphasized.

#### What are some examples of things that use calculus?

Electronic control systems for anything that moves (cars, planes, missiles, machinery.) All of these either use calculus directly, or use further maths which is derived from calculus. In addition to good answers given, some others. Plenty of computer scientists do use calculus, and other important math.
