How would I write a code to solve a system of equations?
In addition to the answers already posted, be sure to put sym() around each of your equations. That is to say, do the following:...

Warning: Explicit solution could not be found.
This is what you need to do, I think. syms x2a x3 y3 x4 y4 upsilon=acos(x2a/6.85) x3=47.5+5.35*cos(upsilon) y3=5.3...

Question

Why does vpasolve work where solve doesn't for the following:
When I pass the following equations into solve like so eqn1 = (120*Lt*pi*Rt)/(14400*Lt^2*pi^2 + Rt^2)^(1/2) - 3389209018899...

Question

How can I create a symbolic vector of functions that dsolve will recognize as variable dependent functions. Need to do this in order to symbolically solve a system of ODEs.
I understand that to create individual time or space dependent functions, I can do the following: syms V1(z) V2(z) V3(z) .....
