Find a vector which is orthogonal to the plane z = 2x-5y + 3. Your vector should be defined as a Python's tuple object named n with syntax just like an ordered n-tuple in math. For example, if you think the answer is vector = (1,2,3), you should write n = (1, 2, 3) (parentheses make n defined as a tuple). ## replace "raise notImplementedError" by your code! # your code here n = (2,-5,-1) Tuples are objects """Check that the variable n is indeed a tuple""" assert type(n) == tuple *""Check whether the answer is correct (hidden test) """
