Trig-SOHCAHTOA

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 sine ratio?

Back

The sine ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle (Sine = Opposite/Hypotenuse).

Front

What is the cosine ratio?

Back

The cosine ratio is defined as the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle (Cosine = Adjacent/Hypotenuse).

Front

What is the tangent ratio?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle (Tangent = Opposite/Adjacent).

Front

How do you find the missing angle in a right triangle using trigonometric ratios?

Back

To find a missing angle, you can use the inverse trigonometric functions: sin^(-1), cos^(-1), or tan^(-1) based on the sides you know.

Front

If the opposite side is 5 m and the hypotenuse is 13 m, what is sin(A)?

Back

sin(A) = Opposite/Hypotenuse = 5/13 ≈ 0.3846.

Front

If the adjacent side is 12 m and the hypotenuse is 13 m, what is cos(A)?

Back

cos(A) = Adjacent/Hypotenuse = 12/13 ≈ 0.9231.

Front

If the opposite side is 5 m and the adjacent side is 12 m, what is tan(A)?

Back

tan(A) = Opposite/Adjacent = 5/12 ≈ 0.4167.

Front

What is the formula to find the length of a side using the sine function?

Back

The formula is: Opposite = Hypotenuse * sin(A).

Front

What is the formula to find the length of a side using the cosine function?

Back

The formula is: Adjacent = Hypotenuse * cos(A).
