Trig Flashcardizz for Finite

Front

What is the sine function?

Back

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

Front

What is the cosine function?

Back

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

Front

What is the tangent function?

Back

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

Front

What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): c² = a² + b².

How do you solve for x using the sine function?

Back

To solve for x using the sine function, use the equation sin(θ) = opposite/hypotenuse. Rearrange to find x: x = hypotenuse * sin(θ).

Front

How do you solve for x using the cosine function?

Back

To solve for x using the cosine function, use the equation cos(θ) = adjacent/hypotenuse. Rearrange to find x: x = hypotenuse * cos(θ).

Front

How do you solve for x using the tangent function?

Back

To solve for x using the tangent function, use the equation tan(θ) = opposite/adjacent. Rearrange to find x: x = opposite / tan(θ).

Front

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

Back

The relationship is given by the equation: tan(θ) = sin(θ) / cos(θ).

Front

How do you find the angle using the sine function?

Back

To find the angle using the sine function, use the inverse sine function: θ = sin⁻¹(opposite/hypotenuse).

Front

How do you find the angle using the cosine function?

Back

To find the angle using the cosine function, use the inverse cosine function: θ = cos⁻¹(adjacent/hypotenuse).
