# Calculus 4 and 5: student confusion

**Is there such thing as calculus 4?**

**Calculus 4 is an extension course of calculus 3, there is no such a calculus 4. But some universities split calculus 3 into sections and call them calculus 4 or calculus 5.** **Is a context that varies between each university. but in this article, we’re going to mention the 10 important subjects that students study in calculus 4. **

- Lagrange
- calculating double and triple integrals
- vectors fields
- line integrals
- theorems of Green
- curl and vector field
- stock’s theorem
- divergence theorem

**Is there such thing as calculus 5? **

**Normally there is not more than calculus 3, most college programs have from calculus 1 to calculus 3. but some colleges split the context of calculus 3 and add it to calculus 4 and 5. So all subjects that you will find in some programs are originally from calculus 3.**

while some college courses don’t even have calculus 4, they just squeeze the all content into three parts:

- calculus1
- calculus 2
- calculus 3

Some other courses have 8 semesters of calculus, they name each semester by a number.** For this reason, a lot of students get also confused and ask if there is a calculus 7 or 8. **

In general, the calculus 4 that you might be studying in a school might not be completely similar to that of other students in another university study. So instead of saying calculus 5 or 4, you have to name a subject of calculus like:

- multivariable
- partial derivatives
- green therom

naming the subject is the common way to understand what you are studying not a number.

But in general, we’re going to name or notice the calculus 5 subject that you might find in some schools, there are some topics of calculus 5 that some students study in colleges such:

- Ordinary differential equations
- Partial Differential equations
- tensor theorem
- real-analysis
- complete analysis
- Extreme Value Theory

**Conclusion**

**To summarize there is no such calculus 4,5 or calculus 6 or even 7 and 8. You might find them in some school curriculums but it just means a level course. **Principally there are 3 calculus sections, calculus 1,2 and 3 more than that is an extension program of calculus 3 that.

calculus is one complete program, each university decides how it going to split its program into 3, 4, or even 5 sometimes as we talked about in our article.
