Math 4 Mock Final Exam

Front

What is the angle of elevation?

Back

The angle of elevation is the angle formed by the horizontal line and the line of sight to an object above the horizontal line.

Front

How do you calculate the length of a slope using trigonometry?

Back

Use the formula: Length = Height / sin(Angle of Elevation).

Front

What is the cosine of an angle in a right triangle?

Back

Cosine is the ratio of the length of the adjacent side to the hypotenuse.

Front

What is the formula for finding the difference of two functions, (f - g)(x)?

Back

(f - g)(x) = f(x) - g(x).

Front

How do you find the measure of an angle using trigonometric ratios?

Back

Use inverse trigonometric functions: sin^(-1), cos^(-1), or tan^(-1) depending on the known sides.

Front

What is the Pythagorean Theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What is the sine of an angle in a right triangle?

Back

Sine is the ratio of the length of the opposite side to the hypotenuse.

Front

What is the tangent of an angle in a right triangle?

Back

Tangent is the ratio of the length of the opposite side to the adjacent side.

Front

How do you find the inverse sine of a value?

Back

Use the function sin^(-1) to find the angle whose sine is the given value.

Front

What is the relationship between sine, cosine, and tangent?

Back

tan(θ) = sin(θ) / cos(θ).
