F : z → z defined by fno 3n
WebExample 2. One of the most famous recursive de nitions is for the Fibonacci sequence f 0;f 1;f 2;:::. Base Case f 0 = 0, f 1 = 1. Recursive Case (n 2) f n= f n 1 + f n 2. Compute the f Webwhen f(z) = 1 z (z 6= 0): Solution: If f(z) = 1 z for z 6= 0; then f0(z) = lim h!0 f(z +h) f(z) h = lim h!0 1 z +h 1 z h = lim h!0 z (z +h) hz(z +h); that is, f0(z) = lim h!0 h hz(z +h) = lim h!0 1 z(z +h) = 1 z2 for z 6= 0: Question 5.
