Sum Or Difference Formula Calculator: Everything You Need To Know

Introduction

Calculus is a branch of mathematics that deals with the study of change. It is a fundamental tool in various fields, including engineering, physics, economics, and more. One of the essential concepts of calculus is the sum or difference formula, which helps to simplify complex expressions. In this article, we will explore everything you need to know about the sum or difference formula calculator.

What is the Sum or Difference Formula?

The sum or difference formula is a trigonometric identity that helps to simplify trigonometric expressions. It is also known as the angle addition or subtraction formula. The formula is used to find the sine, cosine, or tangent of the sum or difference of two angles. The sum or difference formula is expressed as:

sin (α ± β) = sin α cos β ± cos α sin β

cos (α ± β) = cos α cos β ∓ sin α sin β

tan (α ± β) = (tan α ± tan β) / (1 ∓ tan α tan β)

How to Use the Sum or Difference Formula Calculator?

The sum or difference formula calculator is a powerful tool that helps to simplify trigonometric expressions. The calculator is easy to use and can solve complex trigonometric problems in seconds. Here are the steps to use the sum or difference formula calculator:

Enter the two angles in degrees or radians.
Select the operation (sum or difference).
Select the trigonometric function (sine, cosine, or tangent).
Click on the “Calculate” button to get the result.

Examples

Let’s look at some examples to understand how to use the sum or difference formula calculator.

Example 1

Find the value of sin (30° + 45°).

Solution:

sin (30° + 45°) = sin 30° cos 45° + cos 30° sin 45°

sin (30° + 45°) = (1/2) * (√2/2) + (√3/2) * (√2/2)

sin (30° + 45°) = (√2 + √6) / 4

Example 2

Find the value of cos (60° – 45°).

Solution:

cos (60° – 45°) = cos 60° cos 45° + sin 60° sin 45°

cos (60° – 45°) = (1/2) * (√2/2) + (√3/2) * (√2/2)

cos (60° – 45°) = (√2 + √6) / 4
