✅ Read this: The natural logarithm of a positive, real number a may be defined as the area under the graph of the hyperbola with equation y=1/x between x=1 and x=a. This function is a logarithm because it satisfies the fundamental multiplicative property of a logarithm ln(ab)=ln(a) ln(b). This can be demonstrated by splitting the integral that defines ln(ab) into two parts, and then making the variable substitution x=a.t (so dx=a.dt) in the second part, as shown in this reel.
