Hi,

I have constants which are

G=44*10^3;

b=2.95e-10;

tao=0.02;

k=1.38e-23;

delta_fo=0.5;

epsilon_ref=10^6;

q=1.8;

p=0.3;

And also I have these variables

epsilon_p=[0.001,0.01,0.1,1,10]

T=[773,873,973,1073,1173]

My equation is

sigma_t=tao*G*(1-(((k*T)/(delta_fo*G*b^3*log(epsilon_ref/epsilon_p)))^(1/q))^(1/p))

I want to solve this equation for example epsilon_p=0.001 when T=773.

But can't do anything.Hope anyone can help me.
