Answer 4

Am I missing something?
\[\cos 0 = 1\]Why can't you just evaluate this with substitution and call it a day?

Answer 5

\[\Large \frac{\sin t}{1+\cos t}=2 \frac{\sin \frac{t}{2} \cos \frac{t}{2}}{2 \cos^2 \frac{t}{2}}\]
it will be 0

Answer 6

lol yeah no need to do anything just put 0 :P 0/1=0
