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.
Know MoreThe 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.
Learn more about Data GraphsPie charts are an efficient and easy to read way to represent data in percentages or portions. However, it is sometimes difficult to include absolute numbers on a pie chart instead of percentages, particularly if there are many categories shown in the chart.
Full Answer >Bar graphs, or bar charts, are a way of representing data visually; printable bar charts enable people giving presentations to convey digital information on paper. They are similar to line charts but are often used to show discrete components instead of how something changes over time.
Full Answer >Rows and columns are used to describe the arrangement of sets of data or objects in space, but the difference between these two terms lies is the orientation of the objects. A row has the objects arranged horizontally, and a column has the objects arranged vertically.
Full Answer >A frequency table with intervals is a data table showing summarized data and the number of times a data value occurs. The table features intervals, which are used to organize, interpret and examine data values that fall in the range specified by a particular group.
