could you write integral matlab code

Can you write matlab code

[Star Strider]

What is: ‘cost(u(t))’ ?

[bahadir safak]

Very sorry :((

it is cos(t) X(t)=e^-t*cos(t)

Answer 1

[Roger Stafford]

This is a problem in calculus. The indefinite integral would be:

1/8*(sin(2*t)-cos(2*t)-2)*exp(-2*t) + C

Note that this integral is convergent at the upper limit, +inf, but divergent at its lower limit, -inf.

Dear sir thanks you.
