🦌Review 3 - Piecewise and Trigonometry

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

How do you find sinA if the opposite side is 32 and the hypotenuse is 40?

Back

sinA = opposite/hypotenuse = 32/40.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the range of the function f(x) = -x^2 + 4?

Back

The range is y ≤ 4.

Front

How do you find the value of x in a given equation?

Back

To find x, isolate it on one side of the equation using algebraic operations.

Front

If an equation gives x = 44, what does that mean?

Back

It means that the value of x that satisfies the equation is 44.

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 cos(5π/6)?

Back

cos(5π/6) = -√3/2.

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) = adjacent/opposite.

Front

What is cot(180°)?

Back

cot(180°) is undefined because it involves division by zero.
