Thanks for all your help.

I tried to derivate pi using calculus but i just found a quite different result. Can you spot my wrong please?First i started with equlation of a circle which is: $$x^2+y^2=r^2$$ I am assuming circle's center stands on the center of origin. To reach pi we shoud consider the situation that...

Thanks for all your help.

The question i want to ask is why $$F=\frac{mdv}{dt}=\frac{dmv}{dt}$$ I mean how can we move we in the fraction? Is there are mathematical proof or comes from something else?

Okay. Thanks to everyone who helped.

Can you explain why do we need information of x and y is positive to derivate that?

If we continue 5x+5y= 36xy + 5x Then x=5/36

Okay I've missed the detail. Thanks for all your help

Yes it was wrong as I noticed, I've sent my final work

Well starting equation was: 1000/x=3600+(3600(y-x)+1000)/(x+y) Divide all 200 5/x=18+(18(y-x)+5)/(x+y) Can be written as; 5/x=18+(18y-18x+5)/(x+y) Multiply 18 with (x+y)/(x+y) 5/x=(18x+18y+18y-18x+5)/(x+y) 5/x=36y+5/(x+y)

It's the second one. I put it on the calculator and give the result as x=5/36? I simplified until x/5=x/36y+ 1/36 but cannot get further

Homework Statement What is x ?( Assuming x and y are positive) Homework Equations 1000/x=3600 + (3600(y-x)+1000)/x+yThe Attempt at a Solution [/B] Calculator gives it as x=5/36 but I cannot find a way to get that?

What is definition of heat? And why it's unit is kgm^2/s^2? I couldn't be able to link the unit to the definition.

Okay now I understand that I completely miss understood that question I assumed that x= -5m sin(ω)t not x= -5sin(ωt) Thanks for all your help

I unterstood until last equlation but why θ=ωt? Did I missunderstood something in question?
