## What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relations between angles and the lengths of corresponding sides in triangles. Trigonometry is defined as the study of triangles and the relationships between the angles and sides of triangles. Trigonometry is not just about triangles. Trigonometry is about trig-onometric functions, which are ratios of two sides in a right triangle. These trigonometric functions can be used to relate any information given to an angle of a right triangle. It can be used to solve problems in physics, engineering, and other fields. Trigonometry assignment help can provide you with a clear understanding of the basic concepts so that you can complete your homework on time.

## What are some of the trigonometric ratios?

There are six basic trigonometric ratios: sine, cosine, tangent, cosecant, secant, and cotangent.

• 1

### Sine:

Sine is one-half of the ratio between the length of the side opposite an angle to the hypotenuse (the long side). In our case, we're talking about right triangles (those triangles that have a 90° angle). The hypotenuse is the longest side. The other two sides are called legs. Sine takes an angle as an input and gives you the ratio of the opposite leg to the hypotenuse.

• 2

### Cosine:

Cosine is defined similarly to sine but instead it tells you the ratio of the adjacent leg to the hypotenuse.

• 3

### Tangent:

Tangent is defined as one half of the sinθ/cosθ, where θ is another angle at which you want to know about this relation between legs and hypotenuse. Remember that angles in trigonometry are measured in radians.

• 4

### Cosecant:

Cosecant is one-half of the secθ/cosθ, where θ is another angle at which you want to know the relation between legs and hypotenuse. For those who like formulas: csc(θ) = 1/ sin (θ).

• 5

### Secant:

Secant is one-half of the 1/cosθ, where θ is another angle at which you want to know the relation between legs and hypotenuse. For those who like formulas: sec(θ) = 1/ cos (θ).

• 6

### Cotangent:

Cotangent is one-half of the cotan(θ), where θ is another angle at which you want to know the relation between legs and hypotenuse. For those who like formulas: cot(θ) = 1/ tan (θ).

## What is an inverse function?

An inverse function is a function that "undoes" another function by switching some input value with an output value. For example, you can take y as your input and x as your output, so you can think of y=x. But what about the inverse function, where x is the input and y is the output? It would be written as x=y-1 since x=y⁺¹ means "one over y".

For example, what's sin (60°)? You might say that sin (60°) = 1/2, or 0.5. But if we take this value to the inverse function, then sin (0.5) = 60°! In trigonometry, there is a word for all of these "inverse functions": reciprocals! So reciprocal functions provide many special values in trigonometry: reciprocals of sine and cosine.

## What topics come under trigonometry?

• Angles: We help you understand the basic concepts of angles. Angles are measured in radians or degrees and can be represented by vectors.
• Triangles: A triangle is a three-sided polygon. The Trigonometry assignment help explain different types of triangles such as right-angled, acute-angled, and obtuse-angled triangles.
• Trigonometric Ratios: There are six basic trigonometric ratios which are sine, cosine, tangent, cosecant, secant and cotangent. These ratios can be used to solve problems in physics and other fields.
• Inverse Functions: Inverse functions are a type of function that "undoes" another function.
• Law of Sines: The law of sines is a mathematical rule that states that in a triangle, the three sides are related to each other by the following equation: sin(A) / a = sin(B) / b = sin(C) / c. Trigonometry assignment help can provide you with a clear understanding of this law so that you can complete your homework on time.
