Power Rule Antiderivative Coefficients

Problem

Integrate a polynomial term by term with zero constant: if f(x) = sum_i coeffs[i] * x^i then F(x) = sum_i coeffs[i] * x^(i+1) / (i+1).

Return the antiderivative coefficients in ascending order with a leading 0.0 constant term.

Hint

Divide each coefficient by its new exponent and prepend the integration constant.
