A sine function formula is given by sin x Opposite Side Hypotenuse Perpendicular Hypotenuse This formula helps to determine the value of the sine function sin x which can be determined using the lengths of the Y A sin B x frac C B D and y A cos B x frac C B D The value frac C B for a sinusoidal function is called the phase shift or the horizontal displacement of the basic sine or cosine function If C 0 the graph shifts to
Plot of the Tangent Function The Tangent function has a completely different shape it goes between negative and positive Infinity crossing through 0 and at every radians 180 as shown on this plot At 2 radians 90 and at 2 90 3 2 270 etc the function is officially undefined because it could be 0 sin 0 sin 0 2 pi sin 0 2 cdot 2 pi cdots sin 0 k cdot 2 pi for any integer k This shows the trigonometric functions are repeating These functions are called periodic and the period is the minimum interval it takes to capture an interval that when repeated over and over gives the complete function
