तो, इस 𝑓(𝑥) और इसके फोरियर ट्रांसफॉर्म को इसमें रखने पर, तो पहले हमे यह फोरियर ट्रांसफॉर्म[]मिलता है और फिर यह [] होगा क्योंकि पहले यह [] था।
So, we can now use his inequality to get such integrand which is the square of this[] So, by substituting this 𝑓(𝑥) and its Fourier transform in this, so first we have this Fourier transform [] and then this will be []because it was [].
