y = sin(x+y) cos( x + y )[(1 + y')] = y' cos(x + y ) + y'cos(x + y ) = y' y'-y'cos( x+ y) = cos( x + y ) y'[1-cos(x+y)]= cos(x+y) y'= [cos(x+y)]/ [1-cos(x+y)]
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
X + Y (X + Y) ^2 = (X+Y)(X+Y) Factor = (X + Y)
There are two simple strategies to compare two numbers, X and Y: you can calculate X - Y. If X - Y > 0 then X > Y, if X - Y = 0 then X = Y and if X - Y <0 then X < Y. Or you can calculate X/Y. Provided both are greater than 0, if X/Y > 0 then X > Y if X/Y = 1 then X = Y if X/Y <1 then X < Y
Your question is like this:X+Y=15, X-Y=5, (X x Y)-X+Y= ?According to my calculations, X=10 and Y=5, therefore (X x Y)-X+Y= 45.
