How to solve trig equations with a calculator (and the unit circle)

Learn how to use a calculator (Casio, TI, HP, etc) to solve equations such as sin(theta) = 0.2, cos(theta) = -0.6, tan(theta) = -2, etc, finding all solutions in a given range, for degrees or radians. You do this by using the inverse trig functions (sin⁻¹, cos⁻¹, tan⁻¹). I'll also show you how to find solutions to the nearest minute (how to convert to degrees, minutes, and seconds on a calculator). What's also important is being able to switch your calculator to degrees or radians mode.
