Hi @4500zenja1, and thinks for your help :)

If the instance is a Coordinates instance, then you just need to call .radians property, otherwise you should follow formulas from here, for example.

Hi, and thanks for this awesome kata :)
I'am a beginner and I don't find how to get the latitude and longitude in radians of my instances...
Thanks for your help!

63 = 21 x 3, it is even explained in the kata's description, last example.

Hi, and thanks for this kata.
The fourth basic test seems to be wrong: "[1, 5, 10, 21, 25], 63), 3)"! --> sum([1, 5, 10, 21, 25]) == 62,
so it's not possible to reach 63, so it woulds return 0 and not 3
My bad :(
I didn't understand we could use the same coin more than one time.
So there is not issue!

Thanks for your help, @samhstn : D

Because you differentiate "12x + 2" to give you "12"

Hi,
I do not understand this kata --> why ("12x + 2", 3) should return 12 ???
12 * 3 + 2 == 38
I think I had to miss something :)
Thanks for your help!
