A JSON object is typically represented in the format:{ "key": "value", "key": "value" }
There is no maximum level of nesting allowed in a JSON object, as it can be nested to any level.
The data type not supported in JSON is complex numbers.

Trigonometry

The value of sin(90°) is 1.
The reciprocal of cos(60°) is 2.
In a right-angled triangle, if the length of the base is 6 and the length of the hypotenuse is 10, the value of sin(angle) is 6/10 or 0.6, where the angle is opposite to the base.
