If you can remember the graphs of the sine and cosine functions, you can use the identity above (that you need to learn anyway!) to make sure you get your asymptotes and x-intercepts in the right places when graphing the tangent function. At x = 0 degrees, sin x = 0 and cos x =...

Graphing: Sine and Cosine Section 4.4 – Day 1 Sine and Cosine Graphing: 𝑦=𝑎 sin 𝑏𝜃 and 𝑦=𝑎 cos 𝑏𝜃 Amplitude Definition: The amplitude is 𝑎 . The distance from the x-axis to the curve in a trigonometric graph. “The height of the wave.” The amplitude is ...
Sine and cosine functions are defined for every real number. However, because the other trigonometric functions are defined as fractions, they are not going to be defined when the denominators equal {eq}0. {/eq} We have $$\sin x = 0 \iff x = k\pi ~ \forall ~ k \in \mathbb{Z}...
The Trig Explorer aplet (see page 162) This is a teaching aplet, allowing the student to investigate the properties of sine and cosine graphs in the same interactive fashion as the Quadratic Explorer. The Function aplet is probably the easiest to understand and also the one you will use ...
