Q2 - Review for 2nd Unit Test

Front

What is the sine function?

Back

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

Front

What is the cosine function?

Back

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

Front

What is the tangent function?

Back

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

Front

What is the cotangent function?

Back

The cotangent function, denoted as cot(θ), is the reciprocal of the tangent function, defined as cot(θ) = 1/tan(θ) or cot(θ) = cos(θ)/sin(θ).

Front

What is the secant function?

Back

The secant function, denoted as sec(θ), is the reciprocal of the cosine function, defined as sec(θ) = 1/cos(θ).

Front

What is the cosecant function?

Back

The cosecant function, denoted as csc(θ), is the reciprocal of the sine function, defined as csc(θ) = 1/sin(θ).
