Question

Why isn't tan(f(x))=f'(x)?

Answer 1

because.
\[x = t^3 - 15t^2 + 54t\]

Answer 2

and ofc
\[\Huge42\]

Answer 3

it is if f(x)=sin^-1(e^(x+c)), for some constant c

Answer 4

Yeah that actually turned out to be a fairly interesting differential equation. When the tangent of a function is the tangent line to the function haha.
