Integration by Partial Fractions

Click For Summary
SUMMARY

The integral of the function \(\int \frac{e^t dt}{e^{2t} + 3e^t + 2}\) can be approached using the method of partial fractions. By substituting \(x = e^t\), the denominator can be rewritten as \(x^2 + 3x + 2\), which factors into \((x + 1)(x + 2)\). This allows for the expression to be decomposed into simpler fractions, facilitating the integration process.

Homework Statement


[tex]\[<br /> \int {\frac{{e^t dt}}<br /> {{e^{2t} + 3e^t + 2}}} <br /> \][/tex]

I'm not quite sure how to start this one...Any hints? I tried bringing e^t down to the denominator and multiplying it out which still didn't help. I can't see a way to factor the denominator or split this into a partial fraction.

Thank you.

Why can't you factor the denominator? Denote x = e^t. Can you do it now?
