Tangent #10

Tangent of theta is equal to the y value (cosine) / the x value (sine). A way to find tangent is to remember TOA. The TOA represents that tangent = opposite/adjacent. The tangent is always positive in the first and third quadrants. Tangent graphs are undefined at 90 degrees and 270 degrees and the asymptotes are at pi/2 + kpi. The periods are shorter that the sine and cosine graphs. The x intercepts equal npi. The period is pi/B.
