1 Lesson Plan #055 Name ________________________________ Class: PreCalculus Date: Tuesday February 27th, 2014 Topic: Graphing the reciprocal trigonometric functions Aim: How do we graph the reciprocal trig functions? Objectives: 1) Students will be able to graph the reciprocal trigonometric functions HW# 055: Page 600 #’s 14, 26, 31 Do Now: Compare the graph of y sin x and its reciprocal function How can you use the graph of y=sinx to graph y=cscx? y csc x . Procedure: Write the AIM and DO NOW Get students working! Take attendance Give back work Go over HW Collect HW Assignment #1: How can we use the graph of y = cosx to sketch the graph of y secx? Assignment #2: Sketch the graph of y 2sec x 2 = 2 Assignment #3: Sketch the graph of Assignment #4: A) Sketch the graph of y csc(4 x ) y 2sec( x ) 1 B) State the locations of the vertical asymptotes. C) What is the period for this function? D) State the y-intercept if any? E) Determine if this function is even, odd or neither? F) What is the minimum value of the function in the interval [0.5-1.5]? G) In part F, what is the minimum value? H) What is the value of the function at x = .75? I) In the interval [0.5-1.5], for what value(s) of x is the function equal to 5?
