Websin(x+y)sin(x−y) = 21[cos2y− cos2x] Explanation: We can use the product to sum formula sinAsinB = 21[cos(A− B)− cos(A+B)] ... First of all let's write sin(x− y) = sin(x)cos(y)−cos(x)sin(y) In order to have a better writing for the function: g(x,y) = sin(x)(1+ cos(y))+sin(y)(1−cos(x)) Now this is a ... y′ + sin(x +y) = sin(x− y ... Web8 We need to be able to transform this equation to get rid of the trig functions. To better explain this, this is how the problem before this one was done. (I checked the answer, i got this one right.) sin ( arccos ( x)) We substitute arccos ( x) with the symbol θ . So sin ( θ), where θ = arccos ( x), so cos ( θ) = x. philpot mechanics of materials solutions
