Formula & explanation
y′=ky, y(0)=y₀ ⇒ y(t)=y₀eᵏᵗ

Variables & units

Initial value · y(0)
Numeric value · minimum -1000000, maximum 1000000
Constant rate · k
Numeric value · minimum -10, maximum 10
Time · t
Numeric value · minimum -100, maximum 100

Worked example

y′=0.5y and y(0)=3 give y(2)=3e≈8.154845.

Assumptions

The rate k is constant; its inverse-time units must match the time input.
