Cot / Computation Layer

Calculate the cotangent of angle values (in radians) in a column. Similar to numpy.cot() or 1/tan() in mathematics.

Mathematical form: $$y_i=\cot (x_i)=\frac{\cos (x_i)}{\sin (x_i)}=\frac{1}{\tan (x_i)}$$ where:

• Input domain: all real numbers except $n\pi$ (where n is integer)
• Output range: all real numbers
• Period: $\pi$ radians
• Key points: undefined at $x=0,\pi ,2\pi ,...$

Applications:

• Wave phase analysis
• Periodic motion studies
• Angular measurements

Note: Returns null for undefined points (at multiples of π). Input angles must be in radians.
