SUMMARY

The integral of the function \( a^x \) is proven to be \( \frac{a^x}{\ln(a)} + C \). The proof begins by rewriting the integral as \( \int e^{\ln(a) \cdot x} \, dx \). A substitution is then applied where \( u = \ln(a) \cdot x \), facilitating the integration process. This method effectively demonstrates the relationship between exponential functions and logarithms in integration.

PREREQUISITES

Proving that the integral of (a^x)dx = a^x/(lna)+c ?

Hi, I know that:

∫ax dx = ax / ln(a) + C

Could someone give me a step by step that proves this? thanks a lot!

Here's a trick:

Re-write your integral as:

<br /> <br /> \int e^{lna*x}dx<br />

Then use a substitution:

u = ln(a) * x
 


Beautiful! Thank you :D
