What is theta ? What is its use in mathematics ?  
Asked by abhra | 06 May, 2018, 07:07: PM
answered-by-expert Expert Answer 
1. The Greek letter theta is just used as a variable name, much like x and y. 
    For some reason it is most commonly used to denote an angle.  
    But no, it doesn't have a constant value.
 2. θ is often used  to represent angles in two different planes in three-dimensional geometry. 
  
 3. The most common use is as the angle coordinate in polar coordinates.
