MAT 270 is a more credible course than MAT 265. It basically involves calculus with analytic geometry. The basic concepts are Real numbers, limits and continuity, and differential and integral calculus of functions of 1 variable. Let me brief it below :

**1. Real Numbers **

The type of number we typically use, such as 1, 15.82, −0.1, 3/4, etc.

Whether they are positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers. They are called “Real Numbers” because they are not Imaginary Numbers. Real numbers is really a very easy topic and can be interesting if studied by paying complete attention.

**2. Limits **

Limits are one of the most important topics covered in MAT 270. It includes functions, graphs, and many other complex topics. It is not as easy as real numbers but if you get a grip on it, its addictive.

### 3. ** Continuity **

Continuous functions are, in essence, functions whose graphs can be drawn without lifting up your pen. This may sound simple, but this is in fact a very rich subject. Learn how continuity is defined using limits, and about a main property of all continuous functions — the Intermediate Value Theorem.

**4. Differential calculus of functions **

Differential calculus is one of the two sub-fields of calculus. It is used to study the rate of change of an object with respect to time. It may be complex or easy. You just need to get used to it.

### 5. **Integral Calculus of functions **

Integral calculus is also one of the two sub-fields of calculus.The **integral** is called an indefinite **integral**, which represents a class of **functions** (the antiderivative) whose derivative is the integrand. The Fundamental Theorem of C**alculus** relates the evaluation of definite integrals to indefinite integrals.

MAT 270 doesn’t use any textbooks but a few important software used are Maple for Calculus, Math Forum: Calculus Software, MS-DOS Software for Calculus, and UofA Software Programs. Overall, MAT 270 is fairly easy. It might be more work than people think. Students at ASU, sometimes, get confused in selecting which MAT class to register for.
