how to differentiate v(t) in matlab

To differentiate v(t) in Matlab, you can use the "diff" function. First, define your function v(t) as a symbolic variable in Matlab using the "syms" function:

syms t
v(t) = sin(t^2) + 2*t;

Now, you can use the "diff" function to find the derivative of v(t) with respect to t:

diff_v = diff(v(t), t);

2 lines

The output will be the symbolic expression for the derivative of v(t). If you want to evaluate this derivative at a specific value of t, you can use the "subs" function:

t0 = 2;
diff_v_t0 = subs(diff_v, t, t0);

The output will be the numerical value of the derivative of v(t) at t = 2.
