See graphic addition and explanation

#### Explanation:

(f+g)((x) is performing

the algebraic addition of f and g, for

graph{2sinx+sin(2x) [0, 6.2832, -5, 5]}

graph{(y-2sinx)(y-sin(2x))(2sinx+sin(2x)-y)=0 [0, 6.2832, -4, 4]}

Demonstrative addition is depicted by the line x = 1, for x = 1 radian

See the last local graph, for clarity, in this addition.

graph{(y-2sinx)(y-sin(2x))(2sinx+sin(2x)-y)=0 [0.95 1.05, 0, 3]}
