Answer: x ≈ 1.59688927, −1.60312387, −4.67045686, 4.69039614, 7.872914, −7.91513776, −10.89002194
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Simplify 2*cosx*(2x+30°) + √3=0
Simplify each term.
Apply the distributive property.
- 2 cos ( x ) ( 2 x ) + 2 cos ( x ) * 30 ° + √ 3 = 0
- Multiply 2 by 2
- 4 cos ( x ) x + 2 cos ( x ) *30 ° + √ 3 = 0
- Multiply 30 °by 2
- 4 cos ( x ) x + 60 cos ( x ) + √ 3 = 0
- Reorder factors in 4 cos ( x ) x + 60 cos ( x ) + √3
- 4xcos(x)+60cos(x)+√3=0
- Graph each side of the equation. The solution is the x-value of the point of intersection. x ≈ 1.59688927 , − 1.60312387 , − 4.67045686 , 4.69039614 , 7.872914 , − 7.91513776 , − 10.89002194
