Title Solve Systems of Trig Equations
Description This program is intended to solve systems of equations involving trig functions with 1 or 2 unknown angles, but is also an easy way to handle other types of equations, such as exponential or logarithmic equations or complex trig equations with one unknown. It uses the TI Solve function, but is easier to use since there is no variable list to enter. Angle domains can be entered simply by choosing quadrants from a menu. Restrictions for linear variables, such as x>0 and y>0 and y≤ 5, can be entered. Angles can be displayed in radians (in terms of pi when possible) or degrees. All entries can be edited. Solutions are copied to the Home screen and are stored under the variable names. Several examples are included.
