👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on ...

👉 Learn how to graph a tangent function. To graph a tangent function, we first determine the period (the distance/time for a ...

The tangent is defined as the single point where a straight line meets a curved surface. The tangent can be determined with a collection of mathematical formulas but is most commonly determined by ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.

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 been ...
