Age 15Explain it to a 15-year-oldConnect it to the formula
A complex number's squared modulus is the sum of the squares of its real and imaginary components. This page isolates imaginary component and verifies it in the original relationship. The rule is b=√(c−a²). Its input values are modulus squared, real component, and the main result is imaginary component. For example: real component=-5 and imaginary component=12 produce modulus squared=169.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated complex modulus squared: solve imaginary component relation over the valid real-number domain stated below. The implemented relation is b=√(c−a²), evaluated from modulus squared, real component to produce imaginary component. A complex number's squared modulus is the sum of the squares of its real and imaginary components. This page isolates imaginary component and verifies it in the original relationship. The result loses phase and component signs.
Inputs and valid domain
- modulus squared must be a finite real number.
- real component must be a finite real number.
Important boundary: The result loses phase and component signs.
The formula
b=√(c−a²)
How the calculator works through it
It substitutes modulus squared, real component into the formula and exposes every numerical step above. The main output is imaginary component, accompanied by Reconstructed modulus squared.
Read the result correctly
The imaginary component is the direct answer to “rearrange the complex modulus squared relationship and solve for imaginary component.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
real component=-5 and imaginary component=12 produce modulus squared=169.
Where this model stops being reliable
The result loses phase and component signs.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
