Greetings, I work in the IT dept of a large organization - yesterday I needed help with a Project. 3 people in my group (my group is a subset of the organization, the other subsets are unrelated functions) are familiar with a particular piece of hardware related to the Project, and were all in...

Thanks!

Greetings, I faced with a problem that states - Find slope of the tangent line to 〖 x〗^4 – xy^2+ 4xy^2 = 20,at (1,2) First I set F= x^4 – xy^2+ 4xy^2-20=0 I found dF/dx = 4x^3 + y^2+ 4y^2= 24 ,at (1,2) then dF/dy = 2xy+8xy,=20 at (1,2) …. Armed with this I then made the...

Aha!... I never thought to look at it in that context... just saw the eqn. and started solving "a mile a minute"...thanks for your insight!... Cheers

Thanks for the responses...as a follow up to HallsofIvy - the crux of the solution was deciding how to proceed after solving the first diff eq. - I'm still not clear on what led you to determine that solving the second diff eq for x was not the right way to proceed. Would you have made the same...

Hi sorry for the text jumble...I've managed to pdf and attach my working. Can ayone figure out where I'm going wrong?. Thanks

[b]1. Given i. dx/dt + y = 0; x(0) = 1 : ii. dy/dt + x = 0; y(0) = 0 Solve for the solns of x and y Although these are first order dif eq's I worked them as leading to a second order undetermined coefficients problem First I wrote them as i. x' + y = 0 and ii. y' + x = 0 Eqn. ii...
