To find an angle for the secant, cosecant, and cotangent functions, you have to use the reciprocal identities first to convert the equation so that it has cosine, sine, or tangent. Section 2.4: Solving Right Triangles. The way we write a measurement can be used to indicate how precise the measurement was.

NOTE: Since your calculator does not have a secant key, you will first need to find the cosine of the angle . Do not round this number, which is . Now, find the multiplicative inverse (reciprocal) of this number using your reciprocal key, which is or , in order to obtain the secant of the angle since secant is the reciprocal of cosine.

We create the graph of the cosine function the same way we do for the sine function, using the unit circle and special triangles. To avoid unnecessary work, answer the following questions about the cosine function from the graph on your calculator. 1. The cosine function is usually given by the notation , where ( is measured in . radians. only.

Sine and cosecant functions are reciprocals as well as cosine and secant functions. Understanding what the sine and cosine functions look like that corresponds to the cosecant or secant functions will help you graph secant and cosecant functions. Prior Knowledge. How will prior knowledge connect to and influence the development of the main topic?

Graph the cosine and secant function. Enter the cosine function in y1. Check your window and mode to make sure there are at least two periods of the graph on your screen- one in the 1st quadrant and one in the 2nd quadrant. Enter the secant function in y2. The secant function may need to be entered as .
