For example, a trigonometric function at 270° is the same as at -90°, as their radial lines are the same (you can check it with this calculator) Tan, cot, sec, and csc, calculated from trig identities. Once you know the value of sine and cosine, you can use the following ...
The graph of y=sin(x): The horizontal test fails. We need to restrict the domain to get the inverse function. (How about other parts?) Then it satisfies the horizontal line test, so it has an inverse f−1—sin−1(x) or arcsin(x). (Beware: the first of these notations is a...

The proof has to rely on the geometry of right-angled triangles, since that’s where the sine function comes from.area of ΔOAB< area of wedge OAB< area of ΔOBD sin(x)2<x2<tan(x)2 Multiplying this by 2, we get a really nice inequality which is worth remembering: $$\...
