function with a condition..

Consider the function
y = f(t) = (exp^(-2.3*t))*((-1.2*cos(1.345*t))+(3.4*sin(1.345*t))), t>= 0
(a) Produce a graph of the function along with the two lines defining the region
abs(y) < 0.1.
(b) Use fzero in conjunction with your plot to identify the time τ at which
abs(f(t)) < 0.1 for all t > τ .
...
so For part A..
I did..
syms x t
t >= 0;
f = @(t) (exp^(-2.3*t))*((-1.2*cos(1.345*t))+(3.4*sin(1.345*t)));
y = f;
abs (y) < 0.1
i dont think this is how it should be done...
Since it is my first time using matlab i don't know how to code this..
Can you guys help me out...!!!??
also help me for part B..
i just dont get it.... QQ

What does the exp^(...) syntax mean? What is exp ?
Remove the ^ to get exp(-2.3*t)
