Sin (A/2) Calculator

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Sin (A/2) - Sin (A/2) is the value of the trigonometric sine function of half of the given angle A.
Cos A - Cos A is the value of the trigonometric cosine function of the angle A.

STEP 1: Convert Input(s) to Base Unit

Cos A: 0.94 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

sin_(A/2) = sqrt((1-cos A)/2) --> sqrt((1-0.94)/2)

Evaluating ... ...

sin_(A/2) = 0.173205080756888

STEP 3: Convert Result to Output's Unit

0.173205080756888 --> No Conversion Required

FINAL ANSWER

0.173205080756888 ≈ 0.173205 <-- Sin (A/2)

Tan (A/2)

Go Tan (A/2) = sqrt((1-Cos A)/(1+Cos A))

Sin (A/2)

Go Sin (A/2) = sqrt((1-Cos A)/2)

Cos (A/2)

Go Cos (A/2) = sqrt((1+Cos A)/2)

Tan (A/2) given Sin A and Cos A

Go Tan (A/2) = (1-Cos A)/Sin A

Sin (A/2) Formula

Sin (A/2) = sqrt((1-Cos A)/2)
sin_(A/2) = sqrt((1-cos A)/2)

What is Trigonometry?

Trigonometry is the branch of mathematics that deals with the relationships between the angles and sides of triangles, particularly right triangles. It is used to study and describe properties such as lengths, angles, and areas of triangles, as well as the relationships between these properties and the properties of circles and other geometric shapes. Trigonometry is used in many fields, including physics, engineering, and navigation.
