Using trig functions to solve for missing sides

Front

What is the definition of a trigonometric function?

Back

A trigonometric function relates the angles of a triangle to the lengths of its sides. The primary functions are sine (sin), cosine (cos), and tangent (tan).

What is the sine function?

Back

The sine function, denoted as sin(θ), is defined as 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(θ), is defined as 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(θ), is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.
