chwala replied to the thread Solve this problem that involves induction.@Mark i re-uploaded, i too could not see the highlighted part :biggrin: -
chwala reacted to renormalize's post in the thread Eliminate ##\theta## between a pair of given equations with
Wow.
Actually, it's not all that hard to reduce one to the other. Start from the textbook... -
Express ## f(3) ## and ## f’(3) ## in terms of ## n ## by using $$ f(x)=\frac{x^{n+1}-x}{x-1} $$ and $$...

chwala posted the thread Solve the given differential equation in Calculus and Beyond Homework Help.Ok, i just came up with this ode. How does one go about to solve it? My attempt Let ##M(x,y) =(2xy+\cos y+\dfrac{2y}{x}-\sin x)## and...

chwala replied to the thread Solve the first order linear differential equation.The formal solution to me does not look complete, but i fully understand the view of mathematicians coming to that conclusion.

Like.
You don't! The expression ##y\left(x\right)=e^{x}x^{-x}\left(6\int e^{-x}x^{x+1}dx+k\right)## (where ##k## is an arbitrary constant)... -
chwala replied to the thread Solve the first order linear differential equation.That is exactly, where my problem is. Somehow this should be integrable... hence the reason of the post.

chwala replied to the thread Solve the first order linear differential equation.I think we’re just going round in circles without any meaningful progress. In my mind, I’m very clear on where I had reached and where I...

chwala replied to the thread Solve the first order linear differential equation.Where was it wrong? The missing of the constant ##C##? My understanding is that contant ##C##is embedded on the integral itself as the...

chwala replied to the thread Solve the first order linear differential equation.I thought i already mentioned the last step where I reached, ie finding the I.f ...my problem from that point is solely on how to use...
