Please help!!!!!

I'm in my final year as an undergrad with a programming project.

essentially my problem is that I have 4 integrations (solved as loops), but all 4 need solving at the same time.

m(t+dt) = m(t) + (dt * P(t))
x(t+dt) = x(t) + ((d(t) * v(t))
v(t+dt) = v(t) + dt (P(t) - P(0))
P (t+dt) = m(t+dt) / x(t+dt)

so far I have managed to get m(t+dt) out with values but without * by P(t)

Any comments or tips on how to start solving things simultaneously would be amazing! I've watched most of Bucky's series but still cant get it :( 

If I've missed something on there just say "oi its video x muppet" and ill take the hint :) 


I'm assuming I may have to set up each and a void func then complete the combinations in main()?


Thanks for reading my ramble, and huge massive thanks if you manage to understand this and be able to help, 
Alex

Hi Alex,

The question is, why do you have to solve them simultaneously?
