SUMMARY

The discussion centers on proving that the limit of the sum of two vector-valued functions equals the sum of their individual limits. Specifically, it examines the functions r(t) = and s(t) = , demonstrating that lim(t→a)(r(t) + s(t)) = lim(t→a)[r(t)] + lim(t→a)[s(t)]. The proof relies on the property of limits for vector-valued functions, confirming that the limit operation distributes over vector addition.

Homework Statement



Let r (t)=f(t),g(t),h(t)and s(t)=〈F(t),G(t),H(t)〉.
Show that lim(t→a)(r (t)+s (t))=lim(t→a)[r (t)]+lim(t→a)[s (t)].


Homework Equations





The Attempt at a Solution



I know that if a function r = <f,g,h> and lim(t→a)[r(t)] then lim(t→a)[r(t)] = < lim(t→a)[f(t)], lim(t→a)[g(t)], lim(t→a)[h(t)] >

OK, so what happens if you apply that last statement to ##\lim_{t\to a}(r(t)+s(t))##?
