WebHalf-lifeis in the time units of the X axis. It is computed as ln(2)/K. Spanis the difference between Y0 and Plateau, expressed in the same units as your Y values. The derivative of an exponential decay equals -K*Y. So the initial rate equals -K*Y0. © 1995-2024GraphPad Software, LLC. All rights reserved. WebThe symbol for half-life is t½.
