Re: Quick calculus questionYou will get that if you integrate both sides 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #4 20131027 18:16:52

Re: Quick calculus questionhi mrpace Strictly speaking the dT/dt is not separable like this as it represents 0/0, but it works out ok if you quickly put in integration signs. Now integrate each side. The right hand side is easy as it is just integrate a constant with respect to t. The left hand side is a natural log. As D is just the constant of integration you can replace it with ln(C), another constant. Bring the two log terms together using the rules for logs and then rewrite the expression with e to get the required expression. I've left a few steps for you. Post back if you need more help.
