Trigonometric functions in age part 1

In this post we will be discussing the trigonometric functions in age. Following descriptions represents the function name, it's description, syntax, what it possibly returns, and a sample query.

degrees:

Degrees convert radians into degrees.

Syntax:

degrees(a numeric expression)
A numeric function can be any number or an expression resulting into a number

Returns:

The function returns a agtype float.

Query:

SELECT *
FROM cypher('your_graph_name', $$
    RETURN degrees(3.14159)
$$) as (deg agtype);

Above query will return the number of degrees something close to pi.

radians:

Radians convert radians into degrees.

Syntax:

radians(a numeric expression)
A numeric function can be any number or an expression resulting into a number

Returns:

The function returns a agtype float.

Query:

SELECT *
FROM cypher('your_graph_name', $$
    RETURN degrees(180)
$$) as (deg agtype);

Above query will return the number of radians something close to pi i.e. 3.1415.

pi:

pi() returns the mathematical constant pi.

Syntax:

pi()

Returns:

The function returns a agtype float.

Query:

SELECT *
FROM cypher('your_graph_name', $$
    RETURN pi()
$$) as (p agtype);

Above query will return pi which is 3.1415.

sin:

sin function returns the sine of a number.

Syntax:

sin(a numeric expression)

Returns:

The function returns a agtype float.

Query:

SELECT *
FROM cypher('your_graph_name', $$
    RETURN sin(0.5)
$$) as (s agtype);

Above query will return sin of 0.5.

cos:

cos() returns the cosine of the number provided.

Syntax:

cos(a numeric expression)

Returns:

The function returns a floating point number.

Query:

SELECT *
FROM cypher('graph_name', $$
    RETURN cos(0.5)
$$) as (c agtype);

Above query will return the cosine of 0.5.

tan:

tan() function returns the tangent of a number.

Syntax:

tan(a numeric expression)

Returns:

The function returns a floating point number.

Query:

SELECT *
FROM cypher('your_graph_name', $$
    RETURN tan(0.5)
$$) as (t agtype);

Above query will return the tangent of 0.5.
