In this video, we will learn to solve the equation “2 sin^2 x + 3 sin x + 1 = 0”. The equation “2 sin^2 x + 3 sin x + 1 = 0” is the twenty sixth question of 2.3 section of the book “Trigonometry by Ron Larson”.

Following link of the video explains the proof of the identity sin(pi + x) = - sin(pi + x)

I first factorised 2sin^× + 3sinx +1 to give (2sinx+1)(sinx+1)=0, then I worked the problem.
