If you look at the their graphs (http://study.com/academy/lesson/graphing-sin-cosine-transformations.html) you will see that they are the same wave function but are out of phase. In other words, one is shifted over to the left. Using the right triangle definitions, sine is the ...
A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input.

Sine (sin) and cosine (cos) are fundamental trigonometric functions that play a vital role in various areas of mathematics, physics, and engineering. The sine of an angle in a right-angled triangle is defined as the ratio of the length of the side opposite the angle to the length of the...
Suppose you have a right-angled triangle such as the one you see below. Notice that the hypotenuse is the longest side of the triangle.There are six basic trigonometric functions that are commonly used to solve problems. These are sine function, cosine function, tangent function, cotangent ...
