IM2: Outcome 3 (All Components)

Front

What is the sine function?

Back

The sine function, denoted as sin(x), is a trigonometric function that relates the angle x to the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

Front

What is the cosine function?

Back

The cosine function, denoted as cos(x), is a trigonometric function that relates the angle x to the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.

Front

What is the tangent function?

Back

The tangent function, denoted as tan(x), is a trigonometric function that relates the angle x to the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.
