syms t
f(t)=1/t;
t=2;
t=3;
f(3)-f(2)/3-2
disp(t)

karthik - what exactly is your question? Why do you have this line of code
f(3)-f(2)/3-2
? Is this supposed to be your average (though isn't being assigned to anything)? Be careful here...you may want to add some brackets around the numerator and denominator...

Hi,
Do you want to find average rate or average? Method to find both is given below
syms t
f=@(t) 1./t;
tmin=2;
tmax=3;
average_rate=(f(3)-f(2))/(tmax-tmin) % average rate of f(t) with respect to t
average=integral(f,tmin,tmax)/(tmax-tmin) % average of f(t)
