Hi,
I've one problem in the following task.
My calculations:
I'm defining following function:
def custom_divide(x,y):
if x==0:
return 0
return y/x
Next, I'm calculating all possible values over *GF(16)* for the function *T*
:
F.<a>=GF(16)
for a,b in F^2:
print "x=",a,"y=",b, "T:",a*custom_divide((c+1)*((custom_divide(a,b
))^3+1)+(c^3+c)*((custom_divide(a,b))^2+custom_divide(a,b)),(custom_divide(a
,b))^4+(c+1)*(custom_divide(a,b))^2+1)+(a*b).nth_root(2)
I know that c is not defined in that code but I wrote it there because it
helps me with describing my problem.
*c+1* and *c^3+c* are constants and I don't know how can I write them in my
code. If I'll write:
F.<a>=GF(16)
for a,b in F^2:
print "x=",a,"y=",b, "T:",a*custom_divide((a+1)*((custom_divide(
a,b))^3+1)+(a^3+a)*((custom_divide(a,b))^2+custom_divide(a,b)),(
custom_divide(a,b))^4+(a+1)*(custom_divide(a,b))^2+1)+(a*b).nth_root(2)
then this constants will be equal to the variable *a* and will be change in
every steps, but they should be the same in all cases.
How can I correct my code?
I'll be grateful for any help in this task.
