In this section we define sine cosine and tangent as well as the reciproacla ratios csc sec and cot Call the length of that line b You can then find the cosine of the angle cosine adjacent hypotenuse which is cos b 1 b So b cos which means that the length of the line between the origin and the point on the x axis is cos

This confirms that cosine is an even function since cos x cos x General cosine equation The general form of the cosine function is y A cos B x C D where A B C and D are constants To be able to graph a cosine equation in general form we need to first understand how each of the constants affects the original graph of y Opposite Sine Cosine and Tangent The three main functions in trigonometry are Sine Cosine and Tangent They are just the length of one side divided by another For a right triangle with an angle Sine Function sin Opposite Hypotenuse Cosine Function cos Adjacent Hypotenuse Tangent Function tan Opposite Adjacent

For real number x the notation sin x cos x etc refers to the value of the trigonometric functions evaluated at an angle of x rad If units of degrees are intended the degree sign must be explicitly shown sin x cos x etc Defining Sine and Cosine Functions Now that we have our unit circle labeled we can learn how the x y x y coordinates relate to the arc length and angle The sine function relates a real number t t to the y coordinate of the point where the corresponding angle intercepts the

The range of cosine is equal to 1 1 as the value of cos x oscillated within the interval 1 1 as it is a periodic function and has a period equal to 2 Cosine is one of the important trigonometric ratios The cosine function is simply denoted as cos x It is the ratio of base and hypotenus A unit circle has a center at 0 0 and radius 1 The length of the intercepted arc is equal to the radian measure of the central angle t Let x y be the endpoint on the unit circle of an arc of arc length s The x y coordinates of this

This arc begins at the point 1 0 and ends at its terminal point P t We then define the cosine and sine of the arc t as the x and y coordinates of the point P so that P t cos t sin t we abbreviate the cosine as cos and the sine as sin We can use the equation x 2 y 2 1 to find the lengths of x and y which are equal to cos and sin when the radius is 1 45 Degrees For 45 degrees x and y are equal so y x
