<<ABOUT>> This is a calculator that is centered around matrices and the things that you could do with them. For example, you could use matrices to find the area of non-right angle triangles or solve 2 or 3 variable equations without elimination or substitution, which can take a long time and take many steps. <<HOW TO USE>> When you start the project, you will see a menu and you will type the number in the parenthesis to the right of the option you want. -Finding Area of Triangles: It will ask for the x and y coordinates of the 3 vertices of the triangle and the answer variable on the top left will give you the area. -Solving 2 Variable Equations: It will ask for the a, b, c, d, e and f of the two equations in the system. (ax+by=c / dx+ey=f) and the answer variable on the top left will give you the solution in x and y. -Solving 3 Variable Equations: It will ask for the a, b, c, d, e, f, g, h, i, j, k and l of the three equations in the system. (ax+by+cz=d / ex+fy+gz=h / ix+jy+kz=l) and the answer variable on the top left will give you the solution in x, y and z.
<<HOW I MADE THIS>> I made this using my knowledge on matrices after learning how to use them through BYU Independent Study for Algebra 2 Part 1 Chapter 4. <<CREDITS>> BYU Independent Study Algebra 2 Part 1 Chapter 4
