Question

Chapter: General Solution of Trigonometry Equations

(2 + √3) cos a = 1 - sin a [ Solve it ]

Answer: 2nπ+π/2

Answer 1

$2 + \sqrt{3 } (( { \cos(x \div 2) }^{2} - { \sin(x \div 2) }^{2} ) ={ ( \sin(x \div 2 - \cos(x \div 2) ) }^{2}$
then proceed by sinplifying using algebraic equations and bring it to the form

Answer 2

HOPE THIS IS UR SOLUTION.
