Hi,
I am trying to define a variable (k1) as the expression that is given as one of the possible solutions from the Solve function so that when I have "k1" further in the program, it will use the solution from the Solve function.
Here is the code in question, simplified:
Input: Solve[Eq4==0,k1]
Output: {{k1-> 4.3*(2.4+1.4*c2+Sqrt[4.6*c2^2+2.02*c2^4]},{k1->4.3*(2.4+1.4*c2-Sqrt[4.6*c2^2+2.02*c2^4]}
So then I have been typing k1:= on the next line and copy-pasting this part in to get:
k1:=4.3*(2.4+1.4*c2+Sqrt[4.6*c2^2+2.02*c2^4
So that I can use it in:
Eq3:=m1*k3+m3*k1+c1*c3-c2^2 Solve[Eq3==0,c2]
To get a value for c2. Surely there is a way to avoid copy-pasting? I feel like the . is supposed to come into play, but I don't understand the syntax for it and can't figure out what to search for to use it!
Thanks! Kaitlin
