Consider the error in using the approximation sin(θ) ≈ θ on the interval [−1, 1]. (a) reasoning informally, say where the approximation is an overestimate and where it is an underestimate. p1(θ) is an underestimate for 0 < θ ≤ 1 and is an overestimate for −1 ≤ θ < 0. p1(θ) is an overestimate for 0 < θ ≤ 1 and is an underestimate for −1 ≤ θ < 0. p1(θ) is an overestimate for −1 ≤ θ ≤ 1. p1(θ) is an underestimate for −1 ≤ θ ≤ 1. none of these (b) use the lagrange error bound for pn(x) to bound the error. check your answer graphically on a computer or calculator. (round your answer to two decimal places.) |e2| ≤
