WebFor example, a complex number 1-3i represents the point (1, -3) on the Argand plane. So an imaginary number bi (which can be written as 0 + bi) represents a point (0, b) on the plane and hence it is a point on the vertical axis (imaginary axis). ... an integer, a rational number, or an irrational number.

Let x be an irrational number then what can be said about x2?

WebMay 19, 2016 · To use these imaginary exponents, you simply move the point for 1 x radians around the unit circle. Unless x is a multiple of π/2, you will get a combination of imaginary and real numbers. If x is equal to π, 1 gets translated half of the way around the circle to -1. This is Euler’s formula. WebAn irrational number is any number that cannot be expressed as the ratio of 2 integers. By that definition, I would say that every complex number with a non-zero imaginary component is irrational. Yes. If you want a non-boring idea, first generalise the integers to the Gaussian integers ℤ [i] (that is, the set of all a + bi where a and b are ... WebApr 10, 2013 · Copy.
