Math - Solving Trig Equations
Start by recalling the most important identity. My math teacher calls this "the #1 Identity." sin^2(x) + cos^2(x) = 1 We want to simplify our trig equation by writing everything in terms of sine. Let's solve the #1 Identity for cos^2(x) because we have that in our trig ...

graphing trig functions
You can pick as many x points as you want. The more you plot, the easier it is to plot a smopoth and accurate curve. For the y values that go with each x, you need a calculator, a special slide rule or a table of trig functions. Hardly anyone uses tables or slide rules anymore.
