calculation error in ex_second_order_eq.py #5

Closed jonasstein closed 7 years ago

jonasstein commented 7 years ago

ex_second_order_eq.py should solve z^2 + pz + q = 0 returns an isopleth for

z=0.3
p=-7
q=2

0.9 +  -2.1 + 2 != 0
lefakkomies commented 7 years ago

0.3 * 2 - 7 0.3 + 2 = 0.09 - 2.1 + 2 = -0.01 (0.3 is approximation from nomograph). ^^^^^^^^ ^^^^

Is short, no error found.
