Step-by-step explanation:
By applying <em>trigonometric</em> expressions and <em>algebra</em> properties, the <em>trigonometric</em> equation 1 - cos 12x is equivalent to the <em>trigonometric</em> equation 2 · sin² 6x. (Correct choice: D)
<h3>How to simplify a trigonometric equation</h3>
Herein we have a trigonometric equation which has to be simplified. Simplification procedure consists in applying <em>trigonometric </em>expressions and <em>algebra</em> properties to transform the function from the form f(cos 12x) to the form f(cos 6x). Now we present the solution in detail:
- 1 - cos 12x Given
- 1 - cos² 6x + sin² 6x cos 2x = cos² x - sin² x / (- 1) · a = - a
- 1 - 1 + sin² 6x + sin² 6x cos² x + sin² x = 1 / (- 1) · a = - a
- 2 · sin² 6x Definitions of subtraction and addition / Existence of additive inverse / Modulative property / Result
By applying <em>trigonometric</em> expressions and <em>algebra</em> properties, the <em>trigonometric</em> equation 1 - cos 12x is equivalent to the <em>trigonometric</em> equation 2 · sin² 6x. (Correct choice: D)
