  1. Sorry yeah thats what I meant. Ah right I didn't think of partial fractions thanks.
  2. I ran into this problem here [math]\int {1}{x^2 + 7x + 10}dx[/math] and the only way I can think of to solve this kinda thing is to do a substitution and get [math]u^-1[/math] but in this case I have no idea how to turn the substitute in the du. Is this a trig substitution problem?
  3. My main problem is I don't know why they give me the info "y0 > 0, k >0". I can isolate t and get t = ln0.5 / -k but I'm assuming they give me that extra info so I can figure out what k is in order to fully solve for t.
  4. Solve for t: y0e-kt = y0 / 2 y0 > 0, k >0 I have no idea how to approach this problem. I don't even know what category this falls under so I'm having trouble googling info this type of problem.
