Reciprocal trig ratios traced from sine, cosine and tangent graphs Clear the trace after each graph is drawn
What is special about the point where sine and cosecant intersect? Is this the same for the other graphs? What happens to the sine, cosine and tangent graphs where cosecant, secant and cotangent are undefined (very large +ve or -ve values)? What happens to tangent graph when cotangent is zero?
