Problem 4. Let V be the vector space of all infinitely differentiable functions f: [0, ] -» R, equipped with the inner product f(t)g(t)d (f,g) = (a) Let UC V be the subspace spanned by B = (sinr, cos x, 1) (you may assume without proof that B is linearly independent, and hence a basis for U). Find the B-matrix [D]93 of the "derivative linear transformation" D : U -> U given by D(f) = f'. (b) Let WC V...
Magneticd fields.. Im kinda lost in this sample problem im trying to study.. could someone pls clarify my questuon i wrote in green.. My question is why they used that formula or can u relate that to the formula i shown to u from my book. Whyvthey ignore that part pf the formula for this problem?? Also i dont understand the limit for 1/r could someone pls help explain.. Any helpful help would be appreciated.. a Cary Cos 2气 ps...

Question 4 [12 marks] Some applications of mathematics require the use of very large matrices (several thousand rows for example) and this in turn directs attention to efficient ways to manipulate them. This question focuses on the efficiency of matrix multiplication, counting the number of numerical arithmetic operations (addition, subtraction and multiplication) involved. We start with very simplest case of 2x2 matrices. (a) The standard way of multiplying 2x2 matrices uses 8 multiplications and 4 additions. List the 8 products...
