differentiate v(t) = 9.7 when t=20 in matlab

To differentiate v(t) in Matlab when t=20, we can use numerical differentiation methods such as the forward difference, backward difference, or central difference formula.

Here's an example code using the central difference formula:

main.m
% define the function v(t)
syms t;
v(t) = 9.7;

% define t and h
t = 20;
h = 0.01;

% use central difference formula to approximate derivative
dv = (v(t+h) - v(t-h))/(2*h);

% display the result
disp(dv);

Output:

main.m

2 lines

In this case, we get a derivative of zero because v(t) is a constant function.
