The general solution of | sin ⁡x |= cos ⁡x is (when n ∈Z ) given by

Question

Accepted Answer

Correct answer: D. (d) : | sin ⁡x |= cos ⁡x R.H.S. 0 ∴ x will lie either in the first quadrant or fourth quadrant. In first quadrant In third quadrant sin ⁡x= cos ⁡x sin ⁡x=- cos ⁡x or tan ⁡x=1 tan ⁡x=-1 or x= /4 x=- /4 ∴ General solution is 2 nπ 4.
