What is the cosecant function (csc x)?

Back

The cosecant function is the reciprocal of the sine function. It is defined as csc x = 1/sin x.

Front

What does the inequality 3|d - 4| ≥ 12 represent?

Back

This inequality represents the values of d that are either greater than or equal to 8 or less than or equal to 0.

Front

What is the value of cos^-1(0)?

Back

The value of cos^-1(0) is 90 degrees.

Front

What does the equation xy = 32 represent in the context of area?

Back

The equation xy = 32 represents the area of a rectangle with length x and width y, where the area is 32 square feet.

Front

What is the sine function (sin x)?

Back

The sine function is a trigonometric function defined as sin x = opposite/hypotenuse in a right triangle.

Front

What is the tangent function (tan x)?

Back

The tangent function is defined as tan x = sin x/cos x, representing the ratio of the opposite side to the adjacent side in a right triangle.

Front

What is the relationship between degrees and radians?

Back

Degrees and radians are two units for measuring angles. 180 degrees is equal to π radians.

Front

What is the absolute value function?

Back

The absolute value function, denoted |x|, represents the distance of x from 0 on the number line, always yielding a non-negative result.

Front

What is the secant function (sec x)?

Back

The secant function is the reciprocal of the cosine function, defined as sec x = 1/cos x.
