sin(θ) is the y-coordinate of the point P. 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 ...

Visualizing Functions as Graphs: 1.1: A graph of a functions is a visual representation of the pairs (input, output), in the plane. This applet will help you to understand the connection between the ...

Save guides, add subjects and pick up where you left off with your BBC account. In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where ...

From our ship-mast example before, the relationship between an angle and its tangent can be determined from its graph, shown below. The graphs of sine and cosine are included as well. The three ...

Here's a more traditional demonstration of sine and cosine. You make your way around the circle (black). As you do so, the values of Y translates to sine (red line) and the values of X translate ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions ...

Whether you're tackling calculus problems or preparing for standardized tests, understanding these fundamental relationships will give you a significant advantage.Think of trigonometric identities as ...
