Learn Trigonometry in 2 Hours

Trigonometry is the branch of mathematics that deals with triangles and angles. Contrary to what most students think, the subject is not difficult to understand. To begin with, passing trigonometry will require students to believe in themselves and encourage themselves that they have what it takes to progress. If you follow the steps below, it is possible to learn the subject in 2 hours.

To succeed in trigonometry, you will need to sharpen your algebra and geometry skills. In algebra, you should be familiar with changing the subject of equations, solving simultaneous equations, and understanding linear equations. Geometry is also close to trigonometry and there are areas where you need to focus on problems involving circles. Understand the different types of triangles and the different formulas used in solving triangle problems.

To learn trigonometry in 2 hours, you need to understand right triangles. Compared to other triangles, the right triangle is the easiest to understand. Learn the basics of these angles; you will understand the three ratios well in trigonometry. Right triangles have three sides, hypotenuse, side and opposite. The hypotenuse is the longest side of the triangle.

In addition to learning about angles, you need to understand three proportions. These are sine, cosine and tangent. Sine is calculated by dividing the opposite angle by the hypotenuse while cosine is calculated by dividing the angle adjacent to the hypotenuse. On the other hand, the tangent is calculated by dividing the opposite angle by the adjacent one. A similar way of arriving at the tangent is dividing the sine by the cosine.

Next, learn the basics of other non-right triangles. The ratios used in right-angled triangles don’t play a big role here, but they do come in handy. For right angle triangles, you should understand two important rules; cosine and sine rule. These two rules are used in determining the properties of non-right triangles. Remember that there are three other ratios that you need to understand. These are secant, cosectant and cotangent. These are cosine, sine and tangent coefficients respectively.

When it comes to trigonometry, you will learn how to solve trigonometric equations. These equations usually involve functions and are solved by substituting the equation and causing it to have a single coefficient. For example, you can convert a multiple trigonometric function to have a single ratio by dividing the equation by a trigonometric term. For example, if the equation contains cosine and sine, divide it by the whole by the sine. You also need to understand the different trigonometric identities.

Learning trigonometry is not as difficult a subject as many people think. The key to mastering the subject is to learn the basics and keep practicing until you master it. The above tips can help you cover the subject in just two hours and then, will allow you to learn trigonometry without difficulty.
