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 =...

A cosine function is graphed starting at (0,1). Mark the x-axis 90, 180, 270, and 360 for degrees or their values in radians (pi/2, pi, 3pi/2, 2pi). Since sine relates the ratio of x to the radius of the triangle formed on the unit circle, at 90 (pi/2) the value of ...

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 ...
You can also plot graphs for trigonometric equations (equations that use sine, cosine, and tan, etc.), establish graphs for linear and quadratic inequalities, and even plot graphs for various kinds of functions like modulus, absolute values, and the greatest integer function. Among the maze of...
