Complex numbers are the numbers that are expressed in the form of a+ib where, a,b are real numbers and 'i' is an imaginary number called “iota”. The value of i = (√-1). For example, 2+3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im)..
What area of maths is complex numbers?
Complex numbers are the combination of real and imaginary numbers. The real part can be expressed by an integer or decimal, while the imaginary part has a square that is negative. Complex numbers arise from the need to express negative numbers' roots, which real numbers can't do..
What grade do you learn complex numbers?
Most students take this class during their junior year (11th grade), however, some take it in their freshman or sophomore years. Students are tested on complex numbers in most math classes after algebra 2 as well as on standardized tests such as the ACT, SAT, and SAT math 2 subject test.Mar 19, 2017.

Why complex numbers are important to mechanical engineering students?
Mechanical & Structural Engineers use complex numbers to analyse the vibration of structures in machines, buildings and bridges, the behaviour of fluid flow around aircraft, and that of wind around buildings and bridges, preventing failures such as the Tacoma Narrows Bridge (Please watch the following video)..
Why do we have to learn about imaginary numbers?
Imaginary numbers, also called complex numbers, are used in real-life applications, such as electricity, as well as quadratic equations. In quadratic planes, imaginary numbers show up in equations that don't touch the x axis. Imaginary numbers become particularly useful in advanced calculus..

Complex Numbers: A number that can be represented in form p + iq is defined as a complex number. Here, p and q are real numbers and. i = − 1. . For a complex number z = p + iq, p is known as the real part, represented by Re z and q is known as the imaginary part, it is represented by Im z of complex number z.

Complex numbers let you find solutions that real numbers can't, and they help you understand and model many phenomena in nature, science, and art. In this unit, you'll learn how to create, manipulate, and visualize complex numbers, and how they relate to other areas of math.
Complex numbers are introduced and taught in high school Algebra 2. Complex numbers are introduced primarily in order to extend the notion of roots of all quadratic equations.
