In this video, we learn how to solve trigonometric equations of the form a sin x + b cos x = c, which are more challenging than standard trigonometric equations. We first derive the general method and then apply it to several examples, Timestamps: 0:32 - General Technique and Derivation 8:00 - Problem 1: solving sinx + cosx = sqrt(3/2) 11:54 - Problem 2: solving -sinx + sqrt(3) = 1 15:25 - Problem 3: transformations and finding the max and min values A practice problem is pinned in the comments for you to try on your own. Hopefully you learn something new and enjoy the lesson!
