No worries, thanks!

I'm proud of you Harshdeep

Thanks! :)

Thanks again!

Same issues are happening with #7.. I used t = 60 and t = 10080 for #7 and got 0.003 kg/m^3 and approximately 0 kg/m^3, which don't match the solutions.

Thanks for clearing this up! I got -0.31 for the slope too, but even the textbook corrections said something different. This is what I got for the rest of #6: b) slope = 2.75; vertical asymptote: x = -5 c) slope = -46.0; vertical asymptote: x = -5/3 d) slope = -1.25; vertical asymptote: x = 6
