Why? I am an extension 1 student

Is Wilhelmy's law still tested in the HSC or have they gotten rid of it? Thanks

Re: HSC 2016 3U Marathon I don't have an answer, but you should be correct. Logically, the temperature will increase after t=37, but as the question doesn't give any further information, i think we have to assume that the temperature is deadlocked. Also, is Wilhelmy's law still tested in the...

Re: HSC 2016 3U Marathon But the cooling stops at 37 minutes. Wouldn't you have to calculate something extra instead of just substituting for t?

Re: HSC 2016 3U Marathon I have a question. A body of 200 degrees is put inside a room with temperature 5 degrees. 25 minutes later, the body is 50 degrees. The cooling stops at 37 minutes. If the cooling follows Newton's Law of Cooling, what is the temperature at 38 minutes

Nice Question

no i originally created this thread for me do to. But other people can also do them. So, either way the purpose is being fulfilled

I will post the solutions for some of these questions soon, if no-one answers them

You do realise, that the second question took 350 years to solve right and about 300 pages

Nice questions, but please try to avoid asking joke questions. thanks

I am in year 12 doing mx1

Tbh, i am just bored. Could someone post some very hard math problems. thanks

This thread is for harder inverse trig or algebraic functions or questions that yu need help with on those topics. The only rule is that every question must be answered before another one is asked. Attached is one to start you off, from one of the BOS Trials.

Re: MX1 Calculus Marathon 2016 That is correct. I personally made x the subject and used dx/dy to differentiate before reverting to dy/dx.

This thread is for interesting integrals or derivatives or integrals and derivatives that you need help with. The only rules are that you must keep this to harder 3U and every question must be answered before a new one is asked. Here is one to start you off, differentiate y= 7^ln(x) with...

Re: HSC 2016 3U Marathon nice

Re: HSC 2016 3U Marathon can someone post a hard integration by substitution question, please
