For students studying trigonometry, there are different subjects that must be mastered to achieve academic success. As an example, when it comes to identities, you should understand that they are those equalities that are always true for any value of variables. Their main significance is that it’s possible to replace their members with others. Keep in mind that trigonometric identities are used to provide certain math expressions with more convenient forms. That’s why they play quite an important role in modern mathematics. Once you get a better understanding of this subject, you won’t have any better way to practice algebra than by proving these identities.

In mathematics, you should understand that they are those equalities that include different trigonometric functions and always remain true for any value of occurring variables where both sides are defined. When dealing with geometry, they involve the functions of 1 or more angles, and you need to distinct them from well-known triangle identities that involve not only angles, but also triangle lengths.

Basically, trigonometric identities are quite helpful whenever you need to simplify those expressions that involve trigonometric functions. One of their most significant applications is integrating non-trigonometric functions, and it’s quite a widespread method that involves using a substitution rule with trigonometric functions before simplifying resulting integrals with a certain trigonometric identity.

As a good math student, you need to have the right understanding of what trigonometric identities are all about. They can have different types, and they all should be well-learnt by you. Take into account that some of them are more popular than others, and they include the following:

- Basic identities of 6 well-known trigonometric functions.
- Pythagorean identities. They are called this way because they use the Pythagorean Theorem.
- Angle sum and difference identities. They can tell you whether it’s possible to break down a particular trigonometric function that includes either a subtraction or addition of 2 angles.
- Double-angle identities. They tell students how to simplify trigonometric functions with doubled angles.
- Half-angle identities. They are similar to the fourth group and they tell you how to simplify trigonometric functions with halved angles.
- Sum to product identities. They can show you how to convert the difference or sum of 2 big trigonometric functions into their product.
- Sum trigonometric identities. They are similar to the above-mentioned type because they show users how to go from the product of 2 trigonometric functions to their difference or sum.

These are the most widely used types in trigonometry, so if you succeed to memorize and understand them, you can become a real expert in this field. Don’t forget to learn more about their common uses. For example, these identities are often used to solve specific math problems that require recalling a certain type. Your teachers may ask you to simplify trigonometric problems by substituting in them or prove different statements with their help. This means that you may fail to get high grades if you don’t find out more about trigonometric identities.

It’s all about the branch of mathematics, which involves studying triangles, their types, and characteristics. The good news is that this subject is easy to learn and understand if you apply the right approach. If you find it hard to get started, there are certain tips that will help you.

First, you should improve your key math skills, such as the knowledge of basic terms and definitions. Be sure to practice important algebraic manipulations because it’s one of the basic skills that must be mastered. You also need to know how to change the subjects of equations, solve them, and so on. Take into consideration basic geometry because this discipline is quite closely related to trigonometry and this means that knowing it is important to solve specific problems, including trigonometric identities.

Another crucial step that should be taken is getting more information about the properties of circles and triangle angles. Make sure that you are familiar with a variety of triangle types before you start learning trigonometry. For instance, you should study right-angled triangles, and the good news is that this subject is easy. The best thing is that it will provide you with a better grasp of basic trigonometry subjects, such as ratios and trigonometric identities.

It’s advisable to familiarize yourself with the sides of such triangles and trigonometric ratios. Once this goal is achieved, feel free to move to non-right triangles and their basic characteristics. The main difference is that they don’t have any right angle, and that’s why 3 trigonometric ratios are less important here, but they still can be used in specific examples. It’s also required to know how to measure all angles in radians, which are alternates to degrees and offer a helpful way to measure angles. Take into account that radians are quite helpful when you need to investigate the key properties of circles, and they are widely used in physics too.

To get better grades, you need to spend enough time on practicing to solve different trigonometric equations before switching to trigonometric identities. They involve trigonometric functions and can be solved simply by manipulating those equations that contain 1 trig ratio. It’s possible to use a few effective methods to convert given equations that include more than 1 ratio into the ones that contain only 1. As an example, you can divide them by a specific trigonometric term or use trigonometric identities.

You shouldn’t overlook a set of helpful tips that will guide you in the right direction. Don’t forget that mathematics is not only a certain way of thinking, but this discipline is also about a number of important formulas that must be learned by students. You need to develop your own concepts and keep sharpening your skills, and this is when your attempts to solve math problems will come in handy. If you think that you’re weak in this subject, be sure to review a set of basic concepts.

Another useful trick that should be remembered is that all trigonometric functions are periodic, and this means that they repeat values after particular angles. Make sure that you know everything about different shapes, including polygons, circles, triangles, and so on. This is what will help you avoid forgetting their basic terms and formulas.

There are many students who will agree that doing their homework is not fun at all, especially when it comes to trigonometry and trigonometric identities. However, it’s one of the most important things that should be done to become a successful college or high school student, and that’s why it can’t be neglected.
