By applying real-life models to Trigonometric Equations, predictions and evaluations can be evaluated and calculated. Determining Which Function to Use is the first step when Using Trigonometry in Word Problems. Whether you are Solving for a Missing Side or Solving for a Missing Angle, we provide you with a variety of tools, such as the Inverse Sine or the Law of Cosines, to solve Trigonometric Equations. Master Trigonometric Equations and prepare for more complex functions in Trigonometry.
