Thanks for replying Here is what i have attempted: d/dx ( R(x)^2* V(x) * (Vo-V(x) ) =0 In reality there should be a π before the R(X)^2= ∏(R(x)^2 Thus it was ought to be d/dx (∏(R(x)^2)*V(x)* (Vo-V(x) ) =0 Where R(x)= αx+r1=0.04x+33 ∏(R(x)^2) =A(x) ‘area’ = (∏(0.04x+33)^2) So...

sorry my bad d/dx ( R(x)^2* V(x) * (Vo-V(x) ) =0 it is to be solved wrt 'V(x)' i have gotten this from a problem related to a wind turbine V(x) must be found as it describes velcoity in the turbine's wake at a distance x from the 1st turbine,so to estimate the windspeed available to...

Hi guys i was wondering how one should tackle a differential eqn with multiple functions of x in it like this: i.e d/dx(R(x)^2*V(x)*(V0-V(x))

so a diff technique will give a diff constant?

Hello I was wondering why in this differential equation they did not use double angle identity, I understand how to get the other result also So 1)Dif eqn: Dy/dx +ycotx= cosx Integrating factor IF= e^ (integrand of cotx) = sinx Solution yIF= integrand of QIF where Q is cotx...

the f(x) simpliefies to x + x^(x+1) -1 do you mean differentiate the x^(x+1) separately i don't think it can work like that? do i not need something to equal something before i can apply the log thing

Homework Statement solve via newt raphson iterative method to 4dp Find the solution x= 1/(1+x^x) to 4dp beginning at x=1 Homework Equations Now the formula for this is x1= x0 – f(x0)/f’(x0) Now what I did was rearrange so f(x)= x( 1+x^x)-1=0 I need to differentiatie...

are you speaking of right hand grip rule? do you mean flemings left hand rule if not how would i use grip rule it to find the force? even so if both the wires are carrying current in same direction right next to each othe rmy thumb points in same direction as do my fingers curl in same direction...

I've read that when currents in two parallel wires are going in the same direction, they attract each other. The same text said that when the currents are going in opposite directions, the two wires repel each other. now i can't porve this for myself as i keep making the folowing mistake can...
