What is Trigonometry?

Trigonometry (often called trig) is the mathematical relationship between sides and angles in a triangle. Dating back to before the 3rd century BC the field has been developed into the modern system we use today. Trigonometry has been an important tool in astronomy, navigation, surveying, engineering, and scientific applications like optics and wave functions. Students and engineers can use trigonometry calculators to solve basic trigonometric functions such as sine, cosine and tangent. A more advanced online trigonometry calculator can support the inverse reciprocal function cosecant, secant and cotangent.

How to solve Trigonometric Problems?

These online calculators make it easy to perform and solve trigonometric ratios. To solve trigonometric problems, you generally need one side and one angle in the triangle. Alternatively, you can solve the problem if you have two sides. Trigonometry calculators use the trig ratios to solve these problems.

What are the Trigonometric Functions?

There are three formulas for basic trigonometric calculations: Sine, Cosine and Tangent. Each formula is valuable for calculating different types of trigonometric functions. Of course, it’s always best to memorize all three formulas rather than rely on an online calculator to do your work for you—but if you’re in a pinch, there are plenty of free online calculators out there that make life easier.

What are some General Trigonometric Functions?

There are two general equations that are used to solve problems involving trigonometric functions. The first is the sum and difference formulas. In these, you can take any of three forms: A-B = cos(C), A+B = cos(C), or B-A = cos(C). Where A and B are sides of a right triangle and C is an angle between those two sides.

Can Trigonometry be used to help when Solving Triangles?

There are three ways to solve a triangle. The first and most common way is to use trigonometric ratios. Use a trigonometric ratio when you have an angle and two sides that create it. Knowing a few of these ratios will allow you to determine all of the other angles and sides, which makes solving triangles quite easy

What does SOH CAH TOA Stand for?

SOA CAH TOA is a way of remembering trigonometric functions. It is a mnemonic that stems from the following: sine (sin) equals opposite over hypotenuse, cosine (cos) equal adjacent over hypotenuse and tangent equal opposite over adjacent. By using these ratios, you can easily solve basic trig problems.
