Using the Calculator - Concept
One tool used throughout Algebra, Trigonometry, and Calculus is a graphing calculator. One thing using a graphing calculator is helpful for is solving systems of equations. We can solve systems of linear equations by using a graphing calculator and matrices. We can also solve systems of nonlinear equations by using a graphing calculator to graph their equations and find the intersection.
