How to solve trig inequalities
WebNov 16, 2024 · First, remember that when we say that a a is less than b b we mean that a a is to the left of b b on a number line. So, is a true inequality. Next, don’t forget how to correctly interpret ≤ ≤ and ≥ ≥. Both of the following are true inequalities. In the first case 4 is equal to 4 and so it is “less than or equal” to 4. WebFirst step: Factor out the inequality. (what times what equals 15 and when added together makes 8?) (x+3) (x+5)<0 Step 2: Solve for x. This inequality has two answers. X can either be -3 or -5, since both, when plugged in for x, will make the inequality equal to zero.

WebIn solving quadratic equalities Sal was showing how to solve for f (x) = 0. Meaning the points at which the f (x) line crosses or intersects the x-axis (=0). In solving quadratic INequalities Sal shows how you can solve for f (x) > 0 or f (x) < 0. Meaning the x coordinates at which point the f (x) line is above (>) or below (<) the x-axis (0).
