Program : A program to evaluate the power series x2 x3 xn ex = 1 + x + --- + --- + ..... + ---- 2! 3! n! , 0 < x < 1 It uses if……else to test the accuracy. The power series contains the recurrence relationship of the type Tn = Tn-1 (---) for n > 1 T1 = x for n = 1 T0 = 1 If Tn-1 (usually known as previous term) is known, then Tn (known as present term) can be easily found by multiplying the previous ter...
