Make sure you have this on your card: T5.1i Graphing Trigonometric Functions Make sure you have this on your card: * amplitude period frequency phase shift y = a*sin b * (x – h) + k vertical translation (or cos) Sin: “0”, Max, “0’, Min, “0’ Cos: Max, “0’, Min, “0’, Max

Opener: Pay attention: Important Information: Use my calculators on the test—failure to heed this will result in a zero  Write BOTH the x coordinates (5) and the y coordinates (3). (Emerald) Make a small thumbnail sketch on your test. THE AXES ARE MINE!!! Seriously, the axis lines are the regular x and y axis. You must translate and shift your graph accordingly. Do not draw more than one cycle!!! Just write the max, middle, and min numbers. Do not put extra numbers in. You will have one picture of a graph that you have to find the equation for. To find the “b” in the equation, count the number of times it cycles.

What is the equation? y = 2 sin x

Lesson: What is the equation? y = sin 3x

What is the equation? y = cos x + 4 or y = 4 + cos x

y = 2 sin 3x + 4 or y = 4 + 2 sin 3x But, OMG! This is not 6!!! What is the equation? y = 2 sin 3x + 4 or y = 4 + 2 sin 3x But, OMG! This is not 6!!!
