Question 148136: Hi,
looking for help with Trig functions.
1: Which is equilvalent to SinӨ+CotӨ+CosӨ=?
2: Find all vertical asymptotes of... F(X)=X/X^2-9
3: Find all solutions in [0,2pi) for the trigonometric equation Cos2x=-1
If you can help thank you!

You can put this solution on YOUR website! 1: Which is equilvalent to SinӨ+CotӨ+CosӨ=?
There are many, many equivalents.
------------------------------------------
2: Find all vertical asymptotes of... F(X)=X/X^2-9
They occur when the denominator is zero and the numerator is not zero.
Vertical asymptotes at x = 3 and at x = -3
------------------------------------------
3: Find all solutions in [0,2pi) for the trigonometric equation Cos2x=-1
If cos(2x) = -1
then 2x = pi or 3pi
then x = pi/2 or (3/2)pi
===============
