I am trying to solve a problem that requires me to use two piecewise functions. I need to integrate them and then solve for a variable that was initially inside of the integral. The best way I have found to do this was to use if statements. Is is possible to integrate a nested if statement like this?
m[y_,x_]=If[x=Lab,(MB*x)/Lab,(MB*(Lac-x)/Lbc)]
mbar1[y_,x_]=If[x=y ,(P*y*(Lab-y)*x)/(Lab*
y),(P*y*(Lab-y)*(Lab-x))/(Lab*(Lab-y))]
mbar2[y_,x_]=If[x=y,(P*(y-Lab)*(Lac-y)*(x-Lab))/(
Lbc*(y-Lab)),P*(y-Lab)*(Lac-y)*(Lac-x)/(Lbc*(Lac-y))]
mbar[y_,x_]=If[y=Lab,mbar1[y,x],mbar2[y,x]]
M=Table[m[y,x]+mbar[y,x],{y,1,0.45*Lac,0.05*Lac}]
MatrixForm[k = a1*M + a3*(M)^11]\)
DelBA = Integrate[k*((Lab - x)),{x,o,Lac}]
I have also tried piecewise functions, but the program will not integrate it. Is there another way to do this?
Thanks for any help you can provide.
