Hello,
[(Face Value/PresentValue)^1/Time Period]-1 =[(1000/1200)^0.1]-1 = 1.81% this is different from the example where it is calculated as 8.02%
and the same issue with the second formula: P = (C / 2) x {(1 - (1 + YTC / 2) ^ -2t) / (YTC / 2)} + (CP / (1 + YTC / 2) ^ 2t) =(1090/2)*((1-(1+YTC/2)^-10)/(YTC /2))+(1200/(1+YTC/2)^10) = 529121.28% I tried with 0.076 but getting something strange!!! this is different from the example where it is calculated as 7.6%
