Numpy finding max of function + array

Question

I got these two functions:

mom=-1/2*q*x**2+1/2*q*len*x
quer=-q*x+1/2*q*len

where x is an array defined with numpy:

x=7
q=10
anzahl = 100
x=np.linspace(0, len, anzahl)

I am trying to get the MAX of 'mom' & 'quer" which I get with:

max(mom) & min(mom)

But now I'm trying to get the 'x' value where mom is MAX / MIN

I tried print (x.index(max(mom)) but I think this code doesn't connect the two functions in the right way.

perfect, that was the one I was looking for. What if there are 2 MIN / MAX values - in the docs there is only the case where 1 extreme is found: >>> np.argmax(b) # Only the first occurrence is returned. – KayD Aug 28 '18 at 08:57
If you need all the occurences, you can follow the strategy mentioned here: https://stackoverflow.com/questions/17568612/how-to-make-numpy-argmax-return-all-occurrences-of-the-maximum – Lricsi Aug 28 '18 at 08:59
@LosKayos is this what you were looking for? – Lricsi Aug 28 '18 at 09:07
