Question: dsolve, odeplot and type=numeric

Hello! 
I have this theta model:

And a problem, that sounds like: 
Use Maple's dsolve command with type = numeric, and odeplot
to solve the Theta model for different values of A with the initial condition: 
My question is, how do you use the commands "type = numeric", and "odeplot" to dsolve the model? 
Hope you understand my question, and maybe send a picture of the method to solve this math problem
