expand (x+y)*sin(pi/(x+y))

expand

(x + y) \cdot sin (\frac{π}{x + y})

x sin (\frac{π}{x + y}) + y sin (\frac{π}{x + y})

Solution steps

(x + y) sin (\frac{π}{x + y})

= sin (\frac{π}{x + y}) (x + y)

Apply the distributive law:

a (b + c) = ab + a c

a = sin (\frac{π}{x + y}), b = x, c = y

= sin (\frac{π}{x + y}) x + sin (\frac{π}{x + y}) y

= x sin (\frac{π}{x + y}) + y sin (\frac{π}{x + y})
