Examples

To find the sin of 30 degrees, you divide the length of the opposite side by the hypotenuse.
In a right-angled triangle, the sin of angle A is the ratio of the length of the opposite side to the hypotenuse.
In other words, sin X is equal to Y, right?
If you take a look at that calculation, tan A = so, sin A cos A

So the derivative of sin X is cosine X and then the derivative of cosine X is minus sine X.

Etymology

The math word sin comes from sine, which comes from Latin sinus meaning 'curve' or 'bay'. Long ago, people used words for 'curve' and 'fold' to name the function that makes a wave-like line, so sin now names the ratio that links an angle to the opposite side and the long side of a right triangle.
