1. What is continuity? What is discontinuity? Continuity is a continuous function and a continuos function has no holes, no breaks, a...

Why is a "normal" tangent graph uphill, but a "normal" cotangent graph downhill? If we think back to the unit circle we...

How do graphs of sine and cosine relate to each of the others?   All of the graphs are graphed with an asymptote, they are all graphed when...

Why do sine and cosine NOT have asymptotes, but the other four trig graphs do?  The ratio for sine is y/r and the ratio for cosine is x/r....

1. How do the trig graphs relate to the Unit Circle? Trig graphs relate to the unit circle because of ASTC. Whether the quadrant is positiv...

1. Verifying a trig function means to get one side of the problem to equal the other. Think of it as proofs from Geometry. It's related ...
