5.7 Graphs of Other Trigonometric Functions
Here you will extend what you know about rational functions and sine and cosine functions to produce graphs of
the four other trigonometric functions: tangent, secant, cosecant, and cotangent. You will also see how the four
coefficients of a general sinusoidal function affect the new functions in similar ways.
If you already know the relationship between the equation and graph of sine and cosine functions then the other four
functions can be found by identifying zeroes, asymptotes and key points. Are the four new functions transformations
of the sine and cosine functions?

Guidance
Since secant is the inverse of cosine the graphs are very closely related.
