For example, let’s calculate the cosine of angle α in a triangle with the length of the adjacent side equal to 6 and the hypotenuse equal to 8. cos(α) =6/8 cos(α) =3/4 Cosine Graph If you graph the cosine function for every possible angle, it forms a repeating up/down curve...
How do you graph a cosine function? A cosine function is graphed starting at (0,1). Mark the x-axis 90, 180, 270, and 360 for degrees or their values in radians (pi/2, pi, 3pi/2, 2pi). Since sine relates the ratio of x to the radius of the triangle formed on the unit ci...

Graph the function in radians and describe the domain and range of the function. {eq}\displaystyle\; f(x) = \cos(x - 45^{\circ}) {/eq} Domain and Range of a Cosine Function: A cosine function, along with the sine and tangent functions, is one of...
The cos graph - or cosine graph - is the representation of the cosine function in the Cartesian plane. Like the sine graph, it is a wave.
Solve the equation 2 \sqrt 3 cos \frac{x}{2} = -3 in radians over the interval 0,2\pi). Given cos(x) = 5, how do you find sin (x/2), cos (x/2), and tan (x/2)? 1. Simplify sin (90 - x) + cos x + cos (-x) 2. Use the five key points to graph f(x) =...
