A first-order linear differential equation uses an integrating factor proportional to the exponential of the integrated coefficient. This page isolates initial multiplier and verifies it in the original relationship. The rule is a=ce^(−b). Its input values are integrating factor, integrated coefficient, and the main result is initial multiplier. For example: initial multiplier=1 and integrated coefficient=0.7 produce integrating factor=2.0137527074704766.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated integrating-factor exponential: solve initial multiplier relation over the valid real-number domain stated below. The implemented relation is a=ce^(−b), evaluated from integrating factor, integrated coefficient to produce initial multiplier. A first-order linear differential equation uses an integrating factor proportional to the exponential of the integrated coefficient. This page isolates initial multiplier and verifies it in the original relationship. The coefficient must be integrated with the correct sign before entering the exponent.
Inputs and valid domain
- integrating factor must be a finite real number.
- integrated coefficient must be a finite real number.
Important boundary: The coefficient must be integrated with the correct sign before entering the exponent.
The formula

How the calculator works through it
It substitutes integrating factor, integrated coefficient into the formula and exposes every numerical step above. The main output is initial multiplier, accompanied by Reconstructed integrating factor.
Read the result correctly
The initial multiplier is the direct answer to “rearrange the integrating-factor exponential relationship and solve for initial multiplier.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
initial multiplier=1 and integrated coefficient=0.7 produce integrating factor=2.0137527074704766.
Where this model stops being reliable
The coefficient must be integrated with the correct sign before entering the exponent.
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.
