In using a Riemann sum to approximate an integral, the larger the number of intervals, the more accurate the approximation. If we are approximating \(\displaystyle{\int_0^1(x^2+2)dx}\) using a left Riemann sum, what is the minimum number of intervals needed in order to make the error less than \(0.1?\)
