no matter how small you'd like, and there'll be a rational number in it (actually, there'll be infinity of them). So from an intuitive standpoint, it's probably easiest to think of the exponential as having a nice interpretation on the rational...
Always. Imaginary part? Never. The real part of a positive definite matrix AA is just the average of two positive definite matrices AA and A¯)A¯) and hence it is positive definite. The imaginary part of a positive definite matrix is a matrix with a zero diagonal. ...

A function can have a number of roots. These roots can be real or imaginary. The roots can be solved by setting the function equal to zero and applying any algebraic methods to solve for x.Answer and Explanation: We are given the equation {eq...
Elastic scattering of 14.3 GeV/ c K with protons has been analyzed in the | t | region between 0.005 and 0.550 (GeV/ c) 2. The ratio α between the real and the imaginary part of the elastic forward scattering amplitude is found to be α =+0.056 ± 0.052. The slope parameters A an...
What are the complex numbers? What is the relation between the set of complex numbers, the imaginary numbers, and the real numbers? What is the absolute value of a real number? Where did imaginary numbers come from? Which is both a real number and an integer? (a) 23 (b) 1/4 (...
Limit shapes, real and imaginary Andrei Okounkov ∗ 1 Introduction 1.1 We are surrounded by random surfaces. In fact, every shape around us is random on a sufficiently small scale. The definite shapes that we perceive are manifestations of the law of large numbers that makes averages ...
1. When you try to take the real part and then raise it to the power of 1/4, it might not work as expected due to the complex nature of the expression. 2. The error in the for loop is likely due to the way you are trying to index and assign values to 'u'. Since 'u' ...
