Sin & Cos Graphs Section 4.5
OBJECTIVE Sketch graphs of Sine and Cosine and their Transformations
RELEVANCE The universe is full of curves but straight lines are easier to measure. So trigonometry provides the basis for using triangles to measure curved space and objects. Sin and Cos graphs describe oscillations or waves.
Let’s explore the sine graph! • http://www.mathcasts.org/gg/student/trig/sine_unit_circle_degrees.html • http://www.mathcasts.org/gg/student/trig/sine_unit_circle_degrees_plus.html • https://www.geogebra.org/m/zkrCZM2Y • https://www.geogebra.org/m/UjjwuM8p
Let’s explore the cos graph! • https://www.geogebra.org/m/zkrCZM2Y • https://www.geogebra.org/m/UjjwuM8p
Let’s graph it on the calculator. • Make sure the calculator is in radian mode • Type sin(x) in y1 • Press zoom trig • Now let’s look at y = cos(x).
Transformation of sine • http://www.geogebra.org/en/upload/files/english/Roger_Moss/curve_transformations.html
