## Calculus 1 Description
Doctor Math is really proud to introduce its first product, Calculus 1.
The concept is very simple. Doctor Math is sure that learning mathematics becomes very effective, if the students apply their learned theory by solving as many practical problems as possible.

Doctor Math Calculus 1 offers the students more than 280 practical problems. All solutions of problems and their detailed explanations are available as well. The problems cover different fields of mathematics enclosed in the syllabus of the first year calculus of most universities of the world. This app includes the following main topics:
- Real numbers, mathematical induction.
- Functions and limits.
- Differential calculus.
- Application of derivative (Taylor series, extreme value problems, Newton’s Method).
- Integral calculus.
- Application of Integral (Volumes, arc length, area of surface revolution).
- Infinite sequences and series (limits and convergence).

These 7 sections of Calculus 1 are divided into several subsections. Each subsection contains 7 problems. The complexity of problems is increasing with the number of the problem in every subsection. The students have the possibility to solve the problems themselves and compare the results with the answers provided by Doctor Math. If difficulties occur during the solving process or if the answers do not match, then the students can simply click the ”solution” button and see the complete solution with all necessary explanations. Moreover, Doctor
Math includes a button called ”What Should I Know”. The page under this button contains a brief summary of definitions and theorems as well as formulas necessary for solving the problems.
Through the feedback button Doctor Math is wishing to stay in everyday contact with all users. Any remark or question is welcome.

Here is the best part - Doctor Math Calculus1 is completely free.

## Calculus 1 Reviews in United States

### ***** "Incredible"
Extraordinary
-- Lil Mike21, 2023-07-18

### ***** "This app is GOOD"
This is the best app for calculus ever and it is so easy to use and learn how to do calculus
-- snakin bacon, 2022-12-27

### ****- "HELP!!"
App is usually great, but is force closing by itself lately. It doesn’t seem like there’s an update available. Is there something that can be done? Thank you!
-- Grberkh, 2022-10-05

### **--- "1-1 Practice problem 5 answer is wrong"
48510/14700 is 33/10 not 36/10 thus the answer is wrong.
-- dsffsgzfhddgf, 2021-02-16

### ***** "In depth practical course"
It almost covers all the core topics and gives you great start as a fresh student in your uni study

Many thanks for the excellent work
-- 123 as simple as that, 2020-06-28

### ***** "Can you fix the mistake, please?"
It’s amazing! Great for practice and stuff.

(However, there is a mistake! In 
Numbers -> Rational Numbers -> Problem 5,
There is a mistake in step 3-4!

You see, 4851/100 * 10/147 is actually 33/10, not 36/10.
Therefore the solution is actually -100, not -115.)
-- icecream3512, 2019-07-31

### ***** "Amazing app"
I really like that they give examples and solutions that awesome and it's very helpful in terms of actually finding the solutions and they explain the lessons 
I really really really like this app thank you
-- Starsugar123, 2015-12-10

This app is great help. It has what you need to know to succeed in this course and also has some practice problems aside from the context reading, this is great
