Set $x = -1$ and observe that the left hand side is zero, so the right hand side is zero, so $x^2 = 1$. It's arguable whether the …
Webb11 maj 2015 · i = e i π 2. Now we perform the division making use of the exponent rules: 1 i = e i 0 e i π 2 = e − i π 2. If you consult the unit circle (since the magnitude is 1), you will find that a phase of − π 2 corresponds to − i. Alternatively you can apply Euler's formula: e − i π 2 = cos ( − π 2) + i sin ( − π 2) = − i. Webb12 apr. 2024 · This is a fake proof .

WebbThe formal proof for 1+1=2 from metamath uses cardinal numbers instead of ordinal numbers (as DBK indicated in a comment, that's also what Principia Mathematica did), but that seems to make the proof even more difficult. Note however that already formalizing and proving a simple formula like (a,b)= (c,d) -> (a=c ∧ b=d) in ZFC is quite some work. csob fer rastovyWebb10 maj 2024 · Here is the proof that 1+1=2: start with 1 + 1 1 + s (0): by definition of 1 s (1 + 0): by Addition2 s (1): by Addition1 s (s (0)): by definition of 1 2: by the definition of 2... csob finstatWebbThis is a fake proof .
