A=-2.8i + 1.5j + 1.8k
B=3.7i +4.3j +3.4k
Across B=
i j k
-2.8 1.5 1.8
3.7 4.3 3.4
=-2.64i +16.18j -17.59k
answer 19 (c) Cx= -2.64
20 (f) Cy=16.18
21 (e) Cz= -17.59
Could someone help me with part (b) and part (c)? Please make
the solution clear to understand, thanks!
Let H be a separable Hilbert space with basis {e,n}neN and define Pn as the orthogonal projection onto spanfe1,... ,en (a) A sequence of operators Tn e B(H) is said to converge strongly to T if ||Th-T,nh|| converges to 0 for all h E H (note that strong convergence is actually weaker than operator norm convergence-think of this as the difference between...
