Cos A in Terms of Tan A/2 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cos A = (1-Tan (A/2)^2)/(1+Tan (A/2)^2)
cos A = (1-tan_(A/2)^2)/(1+tan_(A/2)^2)
This formula uses 2 Variables

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Tan (A/2): 0.18 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

cos A = (1-tan_(A/2)^2)/(1+tan_(A/2)^2) --> (1-0.18^2)/(1+0.18^2)

Evaluating ... ...

cos A = 0.937233630375823

STEP 3: Convert Result to Output's Unit

0.937233630375823 --> No Conversion Required

FINAL ANSWER

0.937233630375823 ≈ 0.937234 <-- Cos A

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.
