Geometry/Fourier Transform


Dear Prof Azeem

Can we extend Fourier transform equations to all trigonometric functions ?.

viz Tan, Cot, Sec, Cosec other than Sin, Cosine

Can the Fourier series be applied to other trigonometric  functions ?.

viz Tan, Cot, Sec, Cosec other than Sin, Cosine

Thanks & Regards,
Prashant S Akerkar

Hi Prashant,

A Fourier series is a representation of a function as a sum of sines and cosines.  This is a representation over an interval, and the function must be integrable over that interval.

The sines and cosines come from the complex exponential function.  How do you envision extending this to the other trigonometric functions?  Though the others you mentioned are quotients of sines and cosines, I do not how you expect them to be involved here.

Can you perhaps provide an example of what you mean?

Thanks for asking,
