Now that we have the two defining trigonometric functions to work with, we can start generating more. Since we are still working with right angle triangles, the functions of spiral tangent (tansx), spiral cotangent (cotsx), spiral secant (secsx), and spiral cosecant (cscsx), can be found by using their properties in regular trigonometry, as seen below. You may notice that the functions of tangent and cotangent are equal to their spiral counterparts, while those of secant and cosecant, similar to sine and cosine, are tagged along by the Binet's nth term formula.
Our trigonacci family is now complete!
