First, we see that root raised cosine pulse spectrum is a real and even function of frequency, f.
The closed forms of raised cosine and square root raised cosine pulses which are extensively used in digital communications for zero ISI have been reported in many books on Digital Communications without their derivation.
[4] The use of root raised cosine pulses [5] combines Nyquist data transmission with matched filtering against additive white Gaussian noise (AWGN).
