WebWhen you are solving algebraic equations with inequalities, you treat them almost like equations. You may add or subtract on both sides without any difference. When you multiply or divide, however, you must consider whether the operation you are performing will change the nature of the problem. WebJul 8, 2016 · There is an inequality that is very useful in this case: if a, b ∈ R then a sin ( x) + b cos ( x) ≤ a 2 + b 2. To prove this one can find use the Cauchy-Schwarz inequality : a sin x + b cos x = ( a, b) ⋅ ( sin x, cos x) ≤ a 2 + b 2 sin 2 x + cos 2 x = a 2 + b 2 You are being asked to solve sin ( x) − cos ( x) < 1.
WebNov 17, 2024 · This is easy enough to do. All we need to do is subtract 3 from both sides. This gives. 2 x x + 1 − 3 ≥ 0 2 x − 3 ( x + 1) x + 1 ≥ 0 − x − 3 x + 1 ≥ 0 2 x x + 1 − 3 ≥ 0 2 x − 3 ( x + 1) x + 1 ≥ 0 − x − 3 x + 1 ≥ 0. Notice that I also combined everything into a single rational expression. You will always want to do this.
