Use a linear approximation (or differentials) to estimate the given number. sqrt(99.6) so i think i start with f(x)=sqrt(100-x) so f'(x)= 1/2(100-x)^-1/2 (-1) using a=0 f(x)= 10 and f'(x)= -0.05 when using L(x)=f(a)+f'(a)(x-a) where x=a I get 10 + -0.05(x) and then...

Is the only way to check if a set of vectors are linearly indep. is if the det does not equal 0? I have a problem where v1= [1;2;1;-1] v2=[0;2;1;1] v3=[3 1 0 2] but this creates a 3X4 matrix and you can't find the det of this. I am really confused! thanks :D

Let V be the set of all real-valued continuous functions defined on R1. If f and g are in V, we define f ⊕ g by (f ⊕ g)(t) = f(t) + g(t). If f is in V and c is a scalar, we define c f by (c f)(t) = cf(t). Then V is a vector space, which is denoted by C(−&#...
