Applications of matrices include finding the area of a triangle, finding points, solving linear equations and cryptography of data. A matrix is simply a group of numbers, so its applications in the world of mathematics are widely variable.
The area of a triangle is calculated using a determinant, a type of matrix with three rows and columns representing the x and y coordinates of a triangle. The matrix is evaluated for the area. Collinear points can be found using matrices in the same way. The area, however, will evaluate to zero, which means it is a line rather than a triangle.
Cramer's Rule solves a system of equations using matrices. A coefficient matrix is created from the constants in each equation. Data encryption and decryption, or cryptography, also involves matrices and the conversion of a message into units using a key, which makes the interpretation of the message difficult for outsiders.

Full Answer >A stem-and-leaf plot is a method for visualizing data in which the tens digits of the data points are written in a column and the ones digits are written in rows next to them. The tens digits form the stem, and the ones digits are the leaves.
Full Answer >Schematic diagrams show detailed drawings and information of the individual parts that a system or machine consist of and how they interact. Block diagrams describe a system by visually describing, using blocks and arrows, how each individual part interacts with the system as a whole.
Full Answer >Data analysis is conducted by gathering, processing, inspecting, cleaning, transforming and modeling data. There are a variety of tools that are important for modeling data, including both graphical and quantitative techniques. All data analysis requires a strong understanding of mathematical statistics.
