Sine waves have a value of 0 at time=0, and cosine waves have a value of +1 at time=0. Graphs of elementary trig functions allow you to see the graphs of sine, cosine and tangent and their relationship to travelling around a circle. TRIG CHART. The six basic trigonometry functions are sine, cosine, tangent, cosecant, secant and cotangent.
