Find, to the nearest degreee, all values of θ (theta) in the interval:

0 < (or equal)θ<(or equal)180 that satisfy the equation

8 cos^2 θ-2cosθ-1=0

How would I go about doing this? Help is appreciated...

Are aliens real?

Can we take action against this redundancy and rhetorical annoyance?

It would seem to make sense to me, because as I understand it, all celestial bodies which formed over time due to the big bang are now moving further and further away from each other. Can we tell where the big bang happened?

Most scientists now do believe the big bang occurred 13 billion years before. What does this do to the evolutionary theory, if anything? What does this to do religious views?

How for example would you simplify this question?

(a+b)/ (1/c)

The answer is c(a+b) but I was wondering how this is worked out.

Thanks for the help,

10 points to the first reply that answers it best!

Another sample problem for an exam I'm going to take:

Use the Cauchy-Riemann equations to show that an analytic function satisfying |f(z)| = 1 for all z must be a constant. You may assume that the domain is connected.

I know this must be true by Liouville's Theorem, but I can't imagine how to show it as a consequence of the C-R equations.

Thanks!
