Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs ... We can think of this as filling in the hole on the original function. Squeeze Theorem Examples 2.3 The Squeeze Theorem is a very ...

This applet shows how the graphs of sin(θ) and cos(θ) follow directly from the definition of these functions. Move the slider to change the angle. Observe that after the point moves once around the ...

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has ...

Usually we are interested (as in the example ... The graphs of sine and cosine are included as well. Worth mentioning, though beyond the scope of this article, is that these functions relate ...

Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations ...

What do you think the graph of \(y = \cos 2x^\circ\) would look like ... point when \(y = - 1\) The graph looks like: Now try the example questions below.
