Find all solutions in the interval [0, 2π). sec^2x-2= tan^2x no sol pi/3 pi/4 pi/6

8 sec^2 x + 4 tan^2 x − 12 = 0     →     sec^2x = tan^2x + 1

8 [ tan^2x + 1] + 4tan^2x - 12  = 0

8tan^2x + 8 + 4tan^2x - 12  = 0

12tan^2x - 4   = 0     divide through by 4

3tan^2x - 1  = 0

3tan^2x  =  1  

tan^2x  = 1/3      take the square root of both sides

tanx = ±1 / √3

And on the given interval, this happens at     pi/6 , 5pi/6, 7pi/6, 11pi/6

i hope this helps.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
