Review over for test

Angie of elevation

is the height of an object above a particular reference point, often measured in degrees or radians in trigonometry to determine angles.

Angle of depression

is the angle formed by a horizontal line and the observer's line of sight to an object below the horizontal plane. It is often used in applications like navigation and surveying.

SOHCAHTOA

is a mnemonic for remembering the definitions of the sine, cosine, and tangent functions in trigonometry, where 'S' stands for 'opposite over hypotenuse,' 'C' for 'adjacent over hypotenuse,' and 'T' for 'opposite over adjacent.'

What does SOH mean in SOHCAHTOA?

It stands for "Sine = Opposite / Hypotenuse," representing the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle.

What does CAH in SOHCAHTOA ?

It stands for "Cosine = Adjacent / Hypotenuse," referring to the ratio of the length of the side adjacent to the angle to the length of the hypotenuse in a right triangle.

What does TOA mean in SOHCAHTOA?

It stands for "Tangent = Opposite / Adjacent," which describes the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right triangle.
