Graphs of Cosine and Sine. Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with ...

From the graph of the function, we can see that we should be expecting two solutions: one solution between 180° and 270° and the other between 270° and 360°. \(\sin x^\circ = - 0.349\) ...

Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function, we can see that we should be ...
