The line yx is approx the same at the sinx curve for small angles.
The other trig functions the other four trig functions, tangent, cotangent, cosecant, and secant are not sinusoids, although they are still periodic functions. The first portion of the book is an investigation of functions, exploring the graphical behavior of, interpretation of, and solutions to problems involving linear, polynomial, rational, exponential, and. Angle measure angles can be measured in 2 ways, in degrees or in radians. Chapter 1 functions and special angles r r 1 rad introduction what is trigonometry. So, simply put, trigonometry is the study of the measures of triangles.

An investigation of functions is a free, open textbook covering a twoquarter precalculus sequence including trigonometry.
The graphs of ysinx and y1 2 intersect at many points, so there must be more than one solution to the equation. If the terminal side of passes through the point 4,3, find the simplified, exact values of all six trig functions of. This creates an equation that is a polynomial trig function. Example 4 use the inverse sine function to find one solution to. With these types of functions, we use algebraic techniques like factoring, the quadratic formula, and trigonometric identities to break the equation down to equations that are easier to work with.
