McKeague and Turner (both, Cuesta College) cover the usual introductory trigonometry topics: the six functions, right triangle trigonometry, radian measure, graphing and inverse functions, identities and formulas, equations, triangles, and complex numbers and polar coordinates. Appendices review inverse functions, exponential functions, and logarithmic functions. The sixth edition adds a section on graphing the tangent, cotangent cotangent: see trigonometry. , secant secant, in mathematics.
1 In geometry, a secant is a straight line cutting a curve or surface. If it intersects the curve in two different points, as in the secant of a circle, the segment of the secant between the points is called a chord. , and cosecant cosecant: see trigonometry. functions.
