Cosine and sine of an angle θ are defined to ... cos(θ) is the x-coordinate of the point P and, sin(θ) is the y-coordinate of the point P. This applet shows how the graphs of sin(θ) and cos(θ) follow ...

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 ...

Trigonometric graphs can be sketched when you ... relationships in degrees Trigonometric functions can have several solutions. Sine, cosine and tangent all have different positive or negative ...
