Question

How do I go about solving this? I'm not sure where I put things?

Answer 1

You can factor tanx^2-1

Answer 2

Than once you do that you have to set both parts equal to 0

Answer 3

But I can't factor it, can I?

Answer 4

Yes you can cause tanx times tanxis tanx^2 and than -1 times 1 is -1 and when you multiple the tan times -1 ans tan times 1 they will cancel so it will look like (tan-1)(tan+1)=0

Answer 5

Ohhhh okay. so x = 1 or -1?

Answer 6

Tanx will equal those so yes and since the values are between 0 and pi it will be dealing with quadrant 1 and 2 so you will be looking at the 45 degree angle and 135 degree angle

Answer 7

so pi/4 and 5pi/4?

Answer 8

wait no pi/4 and 3pi/4

Answer 9

Yes!

Answer 10

@kayders1997 Tried to another on my own. http://prntscr.com/9puz6h
