# Description

This free app is a math calculator, which is able to calculate the determinant of a matrix. The determinants of following matrices are available:

- 2x2 matrices

- 3x3 matrices

- 4x4 matrices

- 5x5 matrices

- nxn matrices (with more than 5 rows and columns)

Best math tool for school and college! If you are a student, it will helps you to learn!

Note: In linear algebra, the determinant is a value associated with a square matrix. The determinant provides important information when the matrix is that of the coefficients of a system of linear equations, or when it corresponds to a linear transformation of a vector space.

Very good . Buggy... Very helpful app. Would request a dedicated button to refresh all the values to 0. And also better UI. The ads are annoying at top. Put em in the bottom. Will give 5 stars if all the above are fixed.

thanks GK Apps April 7, 2014

i will make it soon GK Apps November 4, 2013

can you give me an example of the determinants. i want to investigate this. Poor Serious Lag when opening and ask for fine GPS location? Why?

Plz improve It always creates force close before we solve. So plz improve it

## Graphing Calculator by Mathlab

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.
