🔹 Propagator

Propagator is a tool designed to compute the uncertainty of a mathematical expression. The result is the variance (σ²), and the standard deviation (σ) is the square root of the variance.

Welcome to v2, which is now available! What’s new?
The previous version is still available here.

🔹 Syntax Guide

🔹 Enter your formula to compute the variance

Examples:

a + b
1.2e-6 * exp(2 + c)
rho * d * epsilon
y = cst_a * x1 + cst_b * x2
a**(1/2), a^(1/2), a**0.5, a^0.5, sqrt(A) or SQRT(a)
