Merging the response of variation in the value of PQ for all four quadrants, we obtained the complete plot of cos x vs x, for one complete cycle of 0 radians to 2π radians (0° to 360°). The plot thus obtained is shown below:...

Therefore, label the y-axis “Ratios” and the x-axis “Angles.” Typically, the angles are measured in radians. On the y-axis, the ratios are just numbers, so there are no units. The y-intercept of the cos function is $1$, so the point $(0, 1)$ is on the graph. Next, plo...
In fact, if you applied a phase shift to either graph, you will get the graph of the other function. Graphing the functions of y=sin(θ)y=sin(θ)y=sin(θ) (in green) and y=cos(θ)y=cos(θ)y=cos(θ) (in blue): If we moved the graph of cosθcosθcosθ to ...
Determine the amplitude and period of each function. Then graph the function. y = sin(x/3) y = 1/2 cos(2x) y = -2sin(3x) Show Video Lesson How to use the unit circle definition of the sine function to make a graph of it? (in radians) ...
Domain and Range of Secant We know that thesecant functionis the ratio of the hypotenuse and the adjacent side in a right-angled triangle. It can also be written as the reciprocal of the cosine function. Therefore the domain of sec x does not contain values where cos x is equal to zero...
Sketch a graph of the function {eq}y = \cos{(x+\pi/4)} {/eq}. Step 1: We will start by shifting a point at (0, 1) to the left {eq}\pi/4 {/eq} radians because c is positive. We will make a point on our plot (in red): Step 2: Next, we will make plots direct...
The graph of the cosine function is shown below, with the {eq}x {/eq}-axis measured in radians. The graph of y = cos(x). The shape of the cosine graph is a sinusoidal wave which oscillates with amplitude 1 around a middle value of 0. Notice that the cosine function has a period...
The graph of a secant can be sketched by first sketching the graph of y = cos (x) and then estimating the reciprocal of cos (x). Take a look at the y = sec (x) and y = cos (x) shown below. As observed, the u-shapes of the secant graph touch the graph of cos (x) at ...
