लाजिस्टिक वृद्धि वक्र में अनंतस्पर्शरेखा (asymptote) तब प्राप्त होती है जब

In the logistic growth equation \( \frac{dN}{dt} = rN(\frac{K-N}{K}) \), when population density \( N \) reaches carrying capacity \( K \), \( K - N = 0 \), making the population growth rate zero, forming an asymptote where \( K = N \).
