1. The problem statement, all variables and given/known data n ∫2n-tdt 0 2. Relevant equations N/A 3. The attempt at a solution I've been wondering about the correct way to deal with this type of integral for quite a long time. To me, the above integral looks like something of the form: n ∫f(n,t)dt 0 n appears in the integrand AND in the limits of integration, how can I integrate in this case? I am just wondering whether n can be treated as a "constant" in the above integral, i.e. can I treat 2^n as a constant and pull the 2^n OUT of the integral and evaluate n ∫2-tdt ? 0 Thank you for explaining!
