Derivative of a function using the Quotient Rule

[@holyshit922]

sqrt(1+sin(x))y = cos(x) sqrt(1+sin(x))= cos(x)/y y' = -1/2 cos(x)/y and we have separable differential equation y'+tan(x)y = -1/2sec(x)y^3 Bernoulli differential equation Your function is particular solution of these differential equations

Very nice practice for the Quoteint Rule. However, we can do it faster by using the trig identity Cos X =Sqrt(1-Sin^2 X) = Sqrt{ (1-Sin X)* (1+Since)} which makes the expression= Sqrt (1-Sin X). Differentiating this is very simple and gets to the answer in one step.
