I did say this was one for the mathematicians, (one of which I am not!).
To determine the resultant magnitude of two (and only two) vectors that make a right angle to each other, the Pythagorean theorem can be used.
So in the above example, the hypotenuse (R) is found by finding the square root of the sum of the squares of the other two sides, (i.e. the vertical (v) and horizontal (h) components).
So:
R = Square root of v² + h²
R = Square root of 1² + 1²
R = Square root of 2
R = 1.4142
