Method 1 Anonymous Function
q = @(t) (6.25* 10^9)/(t+500)^3 ;
q(1)
Method 2
t = 1 ;
q = (6.25* 10^9)/(t+500)^3 ;
If you have an array of t :
t = 0:0.01:10 ;
q = (6.25* 10^9)./(t+500).^3 ;
plot(t,q)

Read about diff. If you want it symbolic read about syms.

q = @(t) (6.25* 10^9)./(t+500).^3
This will work for vectors or arrays of t.

I recommend using the Symbolic Toolbox

Indeed you did email me, but I always assume that email is confidential unless the sender says otherwise. It would not be proper for me to respond in public to confidential information.
