Question 828367: solve for all values of x
1. sec^2x-2=0

You can put this solution on YOUR website!
1. sec^2x-2=0
sec(x) = sqrt(2)
x = 45 degrees or pi/4
---------------------------------
2. csc6x+2=0
csc(6x) = -2
6x = 210 degrees or (7/6)pi
x = 36 degrees or (7/12)pi
---------------------------------
3. 4sinxcosx+2sinx+2cosx+1 = 0
---------------------------------

4. 2cosx-sqrt(2)=0
cos(x) = sqrt(2)/2
x = 45 degrees or pi/4
