Solve cos x = -sqrt(3)/2

In this video, we will learn to find the principal and general solutions to the equation “cos x = - sqrt(3)/2”. The link of the video explaining, the proof of the identity cos(pi - x) = -cos x, has been given below The link of the video explaining, the proof of the identity cos(pi + x) = -cos x, has been given below Other topics of this video are: Solve the equation cos x = - sqrt(3)/2 Find the principal and general solutions to cos x = - sqrt(3)/2 Find the solutions to equation cos x = - sqrt(3)/2 I, Ravi Ranjan Kumar Singh, have produced this video.
