Mathematics - Algebra & Differential Calculus

[quote=jhoijhoi]lol Scrax :P <3 While the questions haven't caused me brain damage yet, I won't rule it out :P[/quote]

[quote=Xiron]Too much knowledge. The niveau is much too high. Penis.[/quote]

[quote=JEFFY40HANDS]*sighs* Thank goodness I'm not any kind of math wizz. It's my weakest subject, but I'll write a book, wax poetic, just talk ALL DAY. No problem. Anywhoo answer is clearly not 3.1459[/quote]

[quote=jhoijhoi]I've had some help on the limits question and the tank draining question, and I'll upload them to the original post soon. lol guys :) Personally, I don't know why I'm studying Physics at uni anyway =.=[/quote]

[quote=theBMB]so were you able to solve the second one?[/quote]

[quote=Symphunny][quote=caucheka] you lost me at l'hopitals rule. calculus was hard man. [/quote] LOLOL same, im just a freshman, good luck jhoijhoi![/quote]

[quote=gabpin]number 3 : V(t) = 100 + 20t in 100 litres, there is 100 * 0.1 = 10g of salt every litre flows in, there is 0.4 g for 101 litres, concentration will be (0.4 *1 + 0.1 *100)/101 = 0.102 for 100+n litres, concentration will be (0.4n + 10)/(100+n) concentration = (8t + 10)/(100 + 20t) C(t) = (4t + 5)/(50 + 10t) I'm not sure igt math is already enough hard and you are askinng me to do it in an other langage XD[/quote]

[quote=doof]cheers... i was trying to do it with a conjugute, but i was thinking 192 is 3 x 4^3 and 2 is sqrt of 4. by lhopitals the answer is 576 too. 9t^2 / 1 / 2sqrt(x)[/quote]

[quote=doof]squeeze therom doesnt apply apply. it involves finding an equation that binds the function between 2 functions. 2nd looks like a laplace transform.[/quote]

[quote=doof]hey jhoijohi, im about to duck out, ill be home at 5. i havent tried, but look at your notes when doing lplace transforms (week 7) F(s) = intergral 0 upto infinity e^-st f(t) dt so, f(x) = t^(x-1)[/quote]
