1. Prove that if a vector valued function r(t) has a constant length then r(t) and r0(t) are orthogonal.?

|r(t)| = constant implies that 1. r(t) either doesn't change with t, r'(t)=0 or 2. its...would change also by the triangle inequality. In either case since 1. r'(t)=0 or 2. r(t) dot r'(t) = r(t)r'(t)cos(90) = 0...

4. 0.2 + r = 0.2r − 0.06 + 0.3r?

0.2 + r = 0.2r − 0.06 + 0.3r Fist, let's simplify the right side side: r + 0.2 = 0.5r − 0.06 Next, isolate r and simplify. (r + 0.2) - 0.5r - 0.2...

9. If R is isomomorphic to R' then is it necessarily true that R/Kern(R) is isomomorphic to R'?

If f is a *surjective* homomorphism from R to R' then R/ker(f) and R'...ker(f) to f(x) is an isomorphism--- so, in particular, R/ker(f) is isomorphic to f(R). But...
