# 4 Best Half Angle Formula Calculator Sites You Can Find

A half angle formula calculator allows you to calculate values of different trigonometric functions for the value of an angle divided by 2.

Half angle formulas are mostly used for standard angles like 30 and its half angle formula 15, 45 and its half angle formula 22.5, and so on.

Half angle formulas can be used to determine the half-angle trigonometric functions even if the original full angle isn’t known, and that is something that the half-angle calculator does.

Trigonometry is a huge part of math and its uses can be seen in a lot of other branches of the subject.

Trigonometric concepts may seem new and modern but it was actually discovered by ancient Greeks around 190 BC.

That is only the written record of trigonometry that can be found, in terms of practicality, trigonometry is just as old as the human race itself.

Half angle formula is a concept that isn’t very well known in trigonometry and only accounts for a small fraction of it.

Many people aren’t aware of this concept and that is why they might feel a bit overwhelmed when they try solving half angle formula, a half angle formula calculator can help a lot in this situation.

You will find a lot of websites that give you access to a half angle formula calculator.

Most of the math calculator and general calculator websites have a calculator like this, so it can be a bit confusing to pin down the best one as there are options that are clearly better than the rest.

This article will list down the best calculators that you can find on the internet, small review for each of the calculators will also be given below so you can find the best half angle formula calculator.

Hopefully, after completing this article the concept of half identities won’t be a problem for you.
