I'm pretty sure that these are lying in the space spanned by f and g: a)cos2x,
e)0. Use common formulas to check it.

It is given that ∫f(x)dx = cos(x) + 1/2(sin(2x)) + 3. f(x) = cos2x - sinx Show that the equation of the normal to the curve y = f(x) is y = (2√3)(x)/9 - (√3π)/27 at the point where x = π/6.
