This is not a programming problem, the problem is that you do not know about trig functions. The tangent function is discontinuous in PI/2 + n*PI, so you should break it to pieces at those intervals.

Explore the amplitude, period, and phase shift by examining the graphs of various trigonometric functions. Students can select values to use within the function to explore the resulting changes in the ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.

In trigonometry, the secant function, commonly abbreviated as sec, is the multiplicative inverse of the cosine function. In other words, sec refers to the ratio of the hypotenuse to an adjacent side ...
