Hi, how to matching this two equation for define a and bc(t):=2.47+0.0036tc(t):=a+bt
You have 2 unknowns, so you need 2 equations.
The best two equations in your case are:
And have mathcad solve these simultaneously:
Hi. If c(t) is given, and you want to get a and b, can use the coeffs symbolic keyword, or evaluate c and c' at t=0.
