Question

Find modulous and amplitude of z=​

Answer 1

Step-by-step explanation:

Given : z=1+3i.

To Find : Modulus.

Solution: z=1+3i. Modulus z = | z | = √1² + 3² ...

Modulus of =1+3i = √10. amplitude of z = arg z = Tan⁻¹( 3/1) =>amplitude of z = Tan⁻¹( 3) ...

amplitude of 1+3i = 1.249 ( as its measured in radian ) Learn more: Geometrically, the modulus of a complex number represents its ...
