use block to generate polynomials all numbers entered one by one with spaces in between. numbers affect polynomial in ascending sequence. ex: input: (5,-0.4,1,2) output: 5x^0 - 0.4x^1 + 1x^2 + 2x^3 input: (1,4,-0.002) output: 1x^0 + 4x^1 - 0.002x^2 second field changes scale. ex: 1 means [screen x(50) & y(50)] : [output x(50) & y(50)] 10 means [screen x(50) & y(50)] : [output x(5) & y(5)]
