I have this equation:

 

2.3 = .5/(1+exp(-.3*i[2]-.5))+.7/(1+exp(-.6*i[2]-.3))

 

When I atempt to solve fori[2] this is the answer I get:

Problem with solution due to RootOf...

y = g/(1+exp(-a-i*c))+h/(1+exp(-b-i*d))

I cannot solve this for i. When I use maple I get a big result with a RootOf function that I don't know how to handle. I've looked around and I cannot find anything that will help me.

 

Can someone please show me how to solve this?

 

Thanks!

Thanks!
