The derivation gives a function of Ipk. It should be a function of Iout. In addition, the exact derivation includes a term for output inductor pk-pk ripple current, which does have a small effect on the shape of the graph when it is plotted.

question - is it ripple current needed or not in power supply? let say Voltage source is 110V and go through bridge rectifier and through capacitor. is it possible to reduce capacitor value? thanks

Good discussion---but please, the verb is damp, not dampen, unless you are dispensing water.
