If you would like to enlarge the graph or make numbers and letters easier to read, you may click on it to open it in a new window. You may then enlarge that window with your mouse. To further enlarge the image, use your browser’s zoom capabilities. On a PC this is usually ctrl shift + (and zooming out is ctrl -). On an Apple computer this is usually apple shift + (and zooming out is apple -). Based on the given figure, find the following values of trigonometric functions. Note that in the graph, “alpha” stands for $\alpha$, and “beta” stands for $\beta$. Your answer should be a radical in simplified form. For example, $\sqrt{8}$ should be simplified into $2\sqrt{2}$. You also need to remove radicals from a fraction’s denominator. For example, $\frac{1}{\sqrt{2}}$ should be converted to $\frac{\sqrt{2}}{2}$. Use sqrt() to represent the square root symbol. For example, if the answer is $2\sqrt{2}$, you should type in 2sqrt(2) or 2*sqrt(2).
