Question

How to estimate the range for which cotx>1

Answer 1

please tell me the method so that i can find out for other ratios also

Answer 2

Hint: Graph y = cot x and see when cot x > 1 (note that cot x = 1 at 45 degrees and 225 degrees).

Answer 3

hmmm no know that but can u please tell me some other instant method or we just need to memorize it by heart

Answer 4

then for inverse trigonometric range it is 0-pi/2

Answer 5

One final hint: The cot of an angle is positive in quadrant 1 and 3. Use that info in conjunction with the hint I gave you earlier and you should clearly see when cot x > 1.
