How do you find the modulus of an argument?

Modulus: The modulus of a complex number z=a+bi z = a + b i is given by |z|=√a2+b2 | z | = a 2 + b 2 . Argument: The argument of a complex number z=a+bi z = a + b i is given by θ=tan−1(ba) θ = tan − 1 ⁡ where −π<θ≤π − π < θ ≤ π .

What is the value of the product 3 2i )( 3 2i )?

13
Answer: The value of the product of (3 – 2i) (3 + 2i) is 13.

What is the modulus and argument of the complex number 1 i √ 3?

Thus, the modulus and argument of the complex number – 1 – i√3 are 2 and – 2π/3 respectively.

How do you find modulus without a calculator?

That’s simple,

  1. Divide the two numbers ( eg. 7/3 = 2.333333)
  2. eliminate the decimal part (i.e., make the 2.33333 → 2) ( If there is no decimal part, the MOD value is 0, eg.
  3. multiply the divisor with the number you just found out ( 3 * 2 = 6)
  4. now subtract the result from the dividend (7 – 6 = 1, which is your MOD value)

What is the modulus and argument of z?

The complex number z is represented by point P. The length of the line segment, that is OP, is called the modulus of the complex number. The angle from the positive axis to the line segment is called the argument of the complex number, z. The modulus and argument are fairly simple to calculate using trigonometry.

What is the formula of argument?

Argument of a Complex Number Formula If OP makes an angle θ with the positive direction of x-axis then z=r(cosθ+isinθ) is called the polar form of the complex number, where r=|z|=√a2+b2 and tanθ=ba is called argument or amplitude of z and we write it as arg (z)=θ.

What is the additive inverse of the complex number 13 2i?

-13 + 2i
The additive inverse of the complex number 13 – 2i is -13 + 2i.

What is the additive inverse of the complex number 8 3i?

8 – 3i
The additive inverse of the complex number -8 + 3i is 8 – 3i.

What is the argument of complex number 1+ 3i?

Thus, the modulus and argument of the complex number -1-√3i are 2 and -2π/3 respectively.
