ERROR: Set::write: : Tag List in {150 Cos[15 t]+5.` Sin[15
t]==0,False}[t_] is Protected.
That means you tried to assign a value to "{150 Cos[15 t]+5.` Sin[15
t]==0,False}[t_]".
Obviously you cannot use the above as a symbol to assign to, as an LHS
of an assignment. Not only because it's wrong (can't assign to an
equation) but because it's Protected. t_ will be proteccted in the
function it's used in automatically. You can unprotect it. Or,
wiser, you can assign the value to a local var.
I have to reiterate the previous complaint. This isn't a forum for
you incorrectly cutting and pasting someone elses code and asking
others to correct the cut and paste for you.
