# Trigonometry at Arithmetic.com

Arithmetic.com is the place where you can get help if you have gotten stuck with the learning process in any area of mathematics. This subject is almost never fancied by students but no matter if they like it or not, they will have to pass it if they want to graduate from high school. On this page of Arithmetic.com you can find out valuable information about trigonometry, trigonometric identities, and similar triangles and so on. Here you can also find interesting trigonometry problems that can help you test your knowledge in this area of mathematics and help you improve it in case you didn’t get things quite right. Read on and find out everything there is to know about trigonometry and the trigonometry laws.

To start off, we shall begin with defining this field and the concepts that revolve around this branch of mathematics. Thus, trigonometry is a part of mathematics that studies triangles, in particular the relationships between their sides and the angles between the sides. This branch of mathematics defines the trigonometric functions which are the ones to describe the relationships mentioned above. These functions can be applied in various sciences and can be also applied to cyclical phenomena. It is estimated that the field evolved somewhere during the 3rd century BC as a part of geometry which was much more focused on astronomical studies. As a general rule, people get to study this field in middle and secondary schools as a separate course or as part of a precalculus curriculum. It has applications in both pure mathematics and applied mathematics as well as in different branches of science and technology. For instance, a specific part of this field is called spherical trigonometry and is crucial in astronomy and navigation since it studies triangles on spheres.

Right triangle trigonometry, isosceles right triangle, and tangents law and trigonometry laws are only some of the concepts one may have to deal with as part of this field. Solving right triangles by using cosines law or sines law as well as knowing the different trigonometry laws are mandatory operations when one studies trigonometry and are some of which people most often get confused by. Working with sines and cosines is also something that most people find difficult o understand and apply. Yet, these operations are crucial in the existence and application of trigonometry so one will need to do their best in learning how these functions work and what the logic behind them is.

The good news is that there are many online resources that may help you get ahead of this subject. Getting help with the numbers and formulas has never been easier especially for those for whom talking to a teacher sounds like a bad idea. The internet offers you a wide range of possibilities to learn more about everything there is to know concerning trigonometry and the best about it is that it is highly accessible, free and better explained.
