Solve cos x = -1/2
In this video, we will learn to find the principal and general solutions to the equation “cos x = -1/2”.
The link of the video explaining, the proof of the identity cos(pi - x) = -cos x, has been given below
• cos(pi - x) | cos(pi - theta)
The link of the video explaining, the proof of the identity cos(pi + x) = -cos x, has been given below
• cos(pi + x) | cos(pi + theta)
