Web@Soviet When ( c, d) is your proposed inverse of ( a, b) ... multiply ( a, b) × ( a a 2 + b 2, − b a 2 + b 2). A (multiplicative) inverse of an element x (in this context) is an x − 1 such that x − 1 x = 1 = x x − 1. It can be shown (in this context) that the inverse is unique. – JP McCarthy Aug 24, 2013 at 9:57 2 WebSince y is an inverse of z, we must have, by ( 1) that y z = z y = 1, and Since x is an inverse of z, we must have that x z = z x = 1, again, so it satisfies the definition of an inverse element given in ( 1). This means that x = 1 ⋅ x = ( y z) x = y ( z x) = y ( z x) = y ⋅ 1 = y Hence, Therefore, x = y = z − 1,

Web5 apr. 2024 · 2 Answers Sorted by: 2 By the definition of multiplicative inverse, $1/i$ satisfies $ (1/i)i=1$. Presumably you know that $i^2=-1$. Then you have that $$ (-i)i=-i^2=1= (1/i)i$$ By cancellation, $-i=1/i$. Share Cite Follow edited Apr 5, 2024 at 5:01 answered Apr 5, 2024 at 4:58 Stella Biderman 30.6k 6 45 90 Add a comment 0
