Thanks once more!
For example 3, at 15:25, should that half-angle identity not be sin^2(theta) = (1/2)*(1-cos(2*theta)) instead, thus changing the answer entirely? It appears that the cos(theta) term is missing the 2 inside the argument
If you keep watching, I fixed the error.
In example 5 for the last part, the second vector should have a 0 on the last coordinate, not a 4. THe answer is still right though.
for Q2, shouldn't it be e^4+(4)?
No because e^0 becomes 1 and 4 -1 will make it 3
In example 1, I think there is a factoring mistake after (x^4+2x^2+1)/4x^2
Nope. It's fine.
