    Sketching trigonometric graphs and manipulating expressions

    Hi there, I really need some help with the following:

    1. a) Sketch the graph of f(x) = sec x for -3π ≤ x ≤ 3π
    b) Write down an expression which explains the relationship between sec x and cos x

    b) secx = 1/cosx
    secx and cosx are reciprocal of each other
