"WebOct 2, 2024 · If you start with − 1 ≤ cos(1 x) ≤ 1 and multiply through by sin(x), you actually need to make sure that sin(x) > 0 in order to preserve the direction of the inequalities. For example, the inequality you wrote down is not true for x = − π / 4, say. So there are actually two cases: x → 0 − and x → 0 +. The spirit is correct though!
