Webb24 feb. 2024 · We then compute Because is diagonal, its inverse is easily computed. Putting everything together, we have and from here we can compute the trace. Alternatively, if there is a nice way to express in the form with having the same shape as respectively, then we can truly remove any Kronecker products from the computation. Webba 2 + b 2 = (a + b) 2 − 2 a b. a 2 + b 2 = (a − b) 2 − 2 a b. Hence, this is the answer.

Whereas a2 − b2 = (a + b)(a − b) is very simple, to factor a2 +b2 requires the use of complex numbers. So a2 +b2 = (a +ib)(a −ib), but there is no other factoring with real number coefficients. a2 +b2 doesn't have a nice factorization over the reals, but over the complex numbers it's the squared magnitude of a + bi, which gives ... WebbSolution. (a 2 + b 2 + 2ab) − (a 2 + b 2 − 2ab) Here, '−' sign precedes the second parenthesis. So, we will remove it and change the sign of each term within the parenthesis. a 2 + b 2 + 2ab − a 2 − b 2 +2ab.
