On the screen 360 degrees 0 ~ cos (x) curve and a straight line f (x) = 45* (y-1)+31 Superposition of graphics. In which cos (x) graphics with "*" that, f (x) with "+" indicated that the point of intersection of the two graphics on the use of f (x) graphical symbols. Graphical superposition of the key is to calculate in the same line, respectively, the two graphics point out the direction of coordinates, the correct position to determine the relationship between each other.
