Question

Mathematics: Using a Graphing Calculator to Solve a Trigonometric Inequality Use the graphing calculator to approximate the solution of tan(x) – 3 2 over -90° SX 5 90°. Round to the nearest hundredth of a degree.

hardwick744 · Accepted Answer

The first essential step to solving for unknown variables (especially if there only is one) is to isolate all terms with the variable to one side of the equation. This is done below:

-(3x - 2) = -4(x + 1) - 4
-3x + 2 = -4x - 4 - 4

Isolating x:

-3x + 4x = - 4 - 4 - 2
x = -10

Therefore, the correct answer is -10.
