Hey I am so lost! I am taking precal and I need to pass these are so questions. Can you show me how please? Thanks!


Show that 6=6sin x is equivalent to 6cos x
------------- ------------
- & cos x -7(1- sin x)



Is the statement an identity? Tan x +cot x = 1
------------
sinx cos x

You're going to have to format your question better - it looks like you're trying to write a fraction, but it isn't at all clear what it is.

For the second one, try substituting sin(x)/cos(x) for tan(x), and cos(x)/sin(x) for cot(x), and you should get it.
