Page 1 of 7 14.1 Graphing Sine, Cosine, and Tangent Functions.
Sine, Cosine and Tangent. Three Functions, but same idea. Right Triangle. Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle.
This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. The Sine, Cosine and Tangent functions express the ratios of sides of a right triangle.
LESSON 8 THE GRAPHS OF THE TRIGONOMETRIC FUNCTIONS Topics in this lesson: 1. SINE GRAPHS 2. COSINE GRAPHS 3. SINE AND COSINE GRAPHS WITH PHASE SHIFTS 4. SECANT AND COSECANT GRAPHS 5. TANGENT GRAPHS 6. COTANGENT GRAPHS 1. SINE GRAPHS Example Use the Unit Circle to graph two cycles of the function y sin x on the interval (0,4 ).
This Trigonometry Graphs Station Activity is designed to help your PreCalculus students with graphing translations for sine and cosine functions. There are 8 station cards in the set. Print each task card and laminate for durability, or place each question in a clear sheet protector.
Properties of the sine graph, cosine graph and tangent graph You may want to look at the lesson on unit circle, if you need revision on the unit circle definition of the trigonometric functions. Graphs of the trig functions A demonstration of the sine graph, cosine graph and tangent graph.
This tells you that, if you look at the graphs of cosine and sine, the graph of the function cosine is just the graph of the function sine but translated to the left by pi over 2. So here's the graph of sine. You translate it to the left by pi over 2. You reach the graph of cosine. So it's pretty much the same curve, but shifted.
Homework resources in Trigonometric Functions - Trigonometry - Math.. This website will define the trig functions of sine, cosine and tangent. You will be able to practice using them by setting up their ratios.. explains inverse functions, and how to graph them. Dave's Short Trig Course.
On the parent graph of tangent, the point equidistant from the x-intercept and the asymptote is located up one unit. If there is a vertical stretch or shrink, this point will move up or down accordingly. I really like to show the students these patterns rather than give them numerical locations ( Math Practice 8 ).
This Homework is meant to solidify the student's understanding of the shape and basic features of both the sine and cosine graphs. They are asked to find the domain and range of the sine graph. They also apply two basic transformations, one vertical translation and one horizontal translation, to the sine graph as well as determine any changes that may have occurred to the domain and range.

Students will practice identifying a trigonometric function given its graph. This activity includes all six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. Graphs 1-6 contain changes to the period and amplitude only; graphs 7-12 include changes to the period and ampl.
