@@avmmathstutorial7348 Ok sir. Will mark be given if we don't write this step.I wrongly put minus outsider the power. Sir I have asked another question. Kindly reply for that Sir.
Sir why have you used the pole of order 2 ( Double pole) to find the residue in the first sum? Can't we use residue of pole of order m? What is the difference between using residue of pole of order m& pole of order 2.pls tell me Sir
In first sum, power value of dinomianor is 2. So we use the residue in pole of order 2(double pole). Residue of pole of order m is general formula for to find the residues. Here in first sum, given order is 2, so we use residue of pole of order m instead of m=2
