WebThe two rules of inequalities are: If the same quantity is added to or subtracted from both sides of an inequality, the inequality remains true. If both sides of an inequality are multiplied or divided by the same positive quantity, the inequality remains true. If we multiply or divide both sides of an inequality by the same negative number, we ... WebIf the inequality is complicated, containing two or more trig functions, solve it in 4 steps. Step 1.Transform the given trig inequality into standard form R[x] > 0 (or < 0). Example. The inequality (cos 2x < 2 + 3sin x) will be transformed into standard form: R[x] = cos 2x - 3sin x …
