Lets say I am having 2 vector a(x,y) and b(x,y) and i were to take : 1)the partial derivative of a(x,y) with respect x multiply by b(x,y) - b*(da/dx) will this be equals to a*(db/dx)

Hi uart..thx for reminding tat \alpha is not an integer:smile: but now I am having trouble again to write down the series coefficient for \alpha \neq integer because it seems to be too many values and not like a general expression could express them all

i evaluated a0,an and bn term i get a0=0 an= 0 when a not equals to n & 1 when a equals to n bn= 0 i know the general Fourier series representation is in : a0/2 + SUM(ancos(nx) + bnsin(nx)) but then I am stuck on how to apply the general term to this case

I'm having problem finding the representation for the Fourier series with function f of period P = 2*pi such that f (x) = cosαx, −pi ≤ x ≤ pi , and α ≠ 0,±1,±2,±3,K is a constant. Any help is appreciated...

im having problem integrating the equation dydx=y^2/x^2 and also dydx=3*y^2/x
