Students may choose to find the asymptotes of the given function and then draw those in along with the csc or sec curves. Students may graph their function using their calculator and choosing an appropriate window. Students will complete a homework assignment where they are asked to graph secant and cosecant functions.

The graph of the Secant function. The secant function is defined by assigning to the angle ( the reciprocal of the x-coordinate of the ordered pair where the terminal side of the angle ( crosses the unit circle (e.g. ). 1. Using the definition of secant, fill in the following chart with the output for the secant …

Evaluating Secant, Cosecant, and Cotangent on a Calculator. Calculators do not have buttons for these functions. You have to use the reciprocal identities to evaluate these trig functions on a calculator. The Reciprocal Identities (Section 1.4)
Activity overview:
The secant line is drawn and the slope of the secant line is displayed. Students will guess a value for c to see if the slope of the tangent line at c is the same as the slope of the secant. First, students will analyze the function . y1 (x) = x2 on the interval (0, 1). Students should be able to successfully find …

When we are given discrete data and asked to find the equation of a tangent line, we must use the secant line as an estimator. If f(x) is interpreted as the distance an object is located from the origin along an x-axis at time x, then. Slope of the secant line from P to Q is the average velocity from P to Q
