In Session 60 recitation, the problem required computing the antiderivative of (1500/100+(t50)^2)7. I understand to use substitution but how did it simplify to be the arctan?

Best ResponseYou've already chosen the best response.1If you use the substitution t5 = 10 tan(theta) then, after you integrate and reverse the substitution, you get theta = arctan((t5)/10). I hope that answers your question!
