I got InterpolatingFunction c[k] as a result of numerical integration NDSolve. Now, I wanted to use c[k] as if it is an ordinary function of k. I wanted to do numerical integration which looks like as follows: NDSolve[ {k'[t]==0.715c[k[t]]+1.0685k[t]/w[k[t]]^.6 -0.00777091k[t](-1.8+4.2k[t]/w[k[t]]+7.1343c[k[t]]/w[k[t]]^.4)/((0.336k[t]/w[k[t]]-2.22045*10^(-16)c[k[t]]/w[k[t]]^0.4)*w[k[t]]^.6) -0.263685k[t](2.8-4.2k[t]/w[k[t]]-11.0978c[k[t]]/w[k[t]]^.4)*w[k[t]]^.3-0.457928w[k[t]]^.4 /. %, k[0]==0.3},k,{t,0,100}] And I received an error message saying: Supplied equations are not ==== [MESSAGE SEPARATOR] ====
