Cos A Cos B Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cos A Cos B = (cos(Angle A of Trigonometry+Angle B of Trigonometry)+cos(Angle A of Trigonometry-Angle B of Trigonometry))/2
cos A cos B = (cos(A+B)+cos(A-B))/2
This formula uses 1 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Cos A Cos B - Cos A Cos B is the product of values of trigonometric cosine functions of angle A and angle B.
Angle A of Trigonometry - (Measured in Radian) - Angle A of Trigonometry is the value of the variable angle used to calculate Trigonometric Identities.
Angle B of Trigonometry - (Measured in Radian) - Angle B of Trigonometry is the value of the variable angle used to calculate Trigonometric Identities.

STEP 1: Convert Input(s) to Base Unit

Angle A of Trigonometry: 20 Degree --> 0.3490658503988 Radian (Check conversion here)
Angle B of Trigonometry: 30 Degree --> 0.5235987755982 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

cos A cos B = (cos(A+B)+cos(A-B))/2 --> (cos(0.3490658503988+0.5235987755982)+cos(0.3490658503988-0.5235987755982))/2

Evaluating ... ...

cos A cos B = 0.81379768134944

STEP 3: Convert Result to Output's Unit

0.81379768134944 --> No Conversion Required

FINAL ANSWER

0.81379768134944 ≈ 0.813798 <-- Cos A Cos B

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.
