I have an equation:
M = A sin(x(t));
and would like to find: dM/dt
is it possible to create symbolic functions without definition? for x(t) I dont have a definition. But I require:
diff(M,t).
How can an arbitrary symbolic function be declared??

A = 9/13; %arbitrary
syms x(t)
M = A * sin(x(t));
diff(M,t)
