Trigonometry Functions

Trigonometric Functions: Sine of an Angle

We first consider the sine role.

The sine of an angle is the ratio of the opposite side to the hypotenuse side.

Sine is usually abbreviated every bit sin. Sine θ can exist written as sin θ.

You may use want to use some mnemonics to assistance you call up the trigonometric functions. One common mnemonic is to call back the Indian Chief SOH-CAH-TOA.

Example:
Summate the value of sin θ in the following triangle.

Solution:

Using the Sine Formula (the SOH formula)
This is part one of a video that teaches how to utilize the SOH formula in high school Trigonometry.

Trigonometric Functions: Cosine of an Bending

Next, we consider the cosine function.

The cosine of an angle is the ratio of the side by side side and hypotenuse side.

Cosine is usually abbreviated as cos. Cosine θ can be written as cos θ.

Example:
Calculate the value of cos θ in the following triangle.

Solution:

Using the Cosine Formula (the CAH formula)
This video illustrates how to use the Cosine formula (the CAH Formula) in high school trigonometry courses.

Trigonometric Functions: Tangent of an Angle (#tangent}

Next, we first consider the tangent function.

The tangent of an bending is the ratio of the opposite side and side by side side.

Tangent is commonly abbreviated as tan. Tangent θ tin can be written every bit tan θ.

Example:
Summate the value of tan θ in the following triangle.

Solution:

Using the Tangent Formula (the TOA formula)
This video illustrates how to utilise the Tangent formula (the TOA Formula) in high school trigonometry.
