Solve for x, and determine the domain my son.(Wink)
Hmm...I'm really not sure how to go about solving for x. Also, how would I determine the domain once I have x?
When you solve a quadratic equation, in some cases you factor. Right.
Well your problem looks a lot like something like this: (X+a)(X+b)=0
and the solutions are: x=-a, x=-b
Can you see my meaning?
Let secx = y
therfore, y = 2 & y = 1/2
Because both values are positive they are in the 1st and 4th quadrant.
in the first quadrant everything is positive, in second quadrant only sin/cosec is positive, in the third quadrant only tan/cot is positive and in 4th quadrant cos/sec is positive.
Is that what u were askin?
So the correct answer is choice "b"?
yes
Okay, thank you.
