To derive v(t) when t = 20 in MATLAB, we need to solve a differential equation that involves v(t). We can do this using the ode45
function which solves initial value problems for ordinary differential equations.
First, we need to set up the differential equation. Let's say we have an equation of the form:
dv/dt = f(t, v)
where f(t, v) is some function of t and v that describes how v changes with respect to time. We also need an initial condition v0 = v(t0), where t0 is the initial time.
We can then use ode45
to solve this differential equation:

In the code above, we define the differential equation as an anonymous function f
. We also set the initial conditions t0
and v0
. Then, we use ode45
to solve the differential equation from t0
to t = 20
. The output of ode45
is the time vector t
and the solution vector v
.
Finally, we get the value of v
at t = 20
by taking the last element of v
. The result is stored in the variable v_at_t20
.
