Hi,
The code below don't work!
f[x_] := x^2 + 2 x - 3
p = {{a, f[a]}}
Animate[ Plot[f[x], {x, -2, 4}, Epilog -> Point[p]], {a, -2, 4}]
But, If I replace the variable p with is evaluation, the code is OK.
Animate[Plot[f[x], {x, -2, 4}, Epilog -> Point[{{a, -3 + 2 a + a^2}}]], {a, -2, 4}]
I want to use the variable in my document. How can I do it?
Thank you.
