SOHCAHTOA Practice

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic for remembering the definitions of the sine, cosine, and tangent functions: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.

Front

What is the formula for Tangent?

Back

Tangent = Opposite/Adjacent.

Front

If the opposite side is 8 and the adjacent side is 12, what is the tangent of the angle?

Back

Tangent = 8/12 = 2/3.

Front

What is the formula for Cosine?

Back

Cosine = Adjacent/Hypotenuse.

Front

If the adjacent side is 28 and the hypotenuse is 41, what is the cosine of the angle?

Back

Cosine = 28/41.

Front

What is the formula for Sine?

Back

Sine = Opposite/Hypotenuse.

Front

If the opposite side is 8 and the hypotenuse is 10, what is the sine of the angle?

Back

Sine = 8/10 = 4/5.

Front

How do you find the missing angle using the sine function?

Back

Use the inverse sine function: θ = sin⁻¹(Opposite/Hypotenuse).

Front

How do you find the missing angle using the cosine function?

Back

Use the inverse cosine function: θ = cos⁻¹(Adjacent/Hypotenuse).

Front

How do you find the missing angle using the tangent function?

Back

Use the inverse tangent function: θ = tan⁻¹(Opposite/Adjacent).
