31. My preferred method works by finding the poles of the function in the complex plane . 32. The function is extended to the complex plane ( except 1 ) by analytic continuation. 33. Not all such systems have efficient algorithms for the evaluation, especially in the complex plane . 34. Start with a unix circle on the complex plane . 35. The eigenvalues of the circle system plotted in the complex plane form a trefoil shape. 36. See Exponential _ function # On the complex plane . 37. The modular group of transformations of the complex plane maps Ford circles to other Ford circles. 38. These zeros thus form a regular lattice in the complex plane as the poles also will. 39. The series converges for | a | and can be analytically continued in the complex plane . 40. I recently picked up on some ideas brought up with Imaginary time and the complex plane .
