What is a complex number ? Definition and examplesA complex number is any number that can be written in the form a + bi where a and b are real numbers. a is called the real part, b is called the imaginary part, and i is called the imaginary unit.Where did the i come from in a...

A fundamental building block of math, doubles are numbers obtained by adding a number to itself or multiplying it by 2. For example, the double of 2 is 4, the double of 5 is 10, and so forth. The seemingly simple idea of doubling forms the basis for complex computations and ...
math is based around operations performed on numerical symbols, ranging from simple addition and multiplication all the way up to complex calculations like vector geometry; all processes that would be impossible without accurate representations for these figures. it’s no surprise that understanding how...
Where Do We Use Compatible Numbers in Math? If we want to find an estimate or to approximate a calculation, we can replace the actual numbers with compatible numbers. They are commonly used to solve problems where some inaccuracy is acceptable or approximation is allowed. The answer won’t be...

We will first define two useful quantities related to an arbitrary complex number z=x+iy.z=x+iy. (a)Modulus:|z|a)Modulus:|z| The modulus, which can be interchangeably represented by |z||z| or r,r, is the distance of the point zz from the origin, so that its numerical value is...
What is a principal argument in complex numbers? Solution Principal argument: The principal argument is the angle between the positive real axis and the line joining the origin and z. The argument of a complex number z=x+iy is, argz=tan-1yx , when x>0 ππargz=tan-1yx+π , when ...
