2015年7月28日 · How do you solve sec x csc x − 2 csc x = 0? Factorize the left hand side and equate the factors to zero. Result : x = ± π 3 + 2πk , k ∈ Z. However, there is no real value of x …

How do you solve sec x csc x = 2 csc x? General solution is x = 2nπ ± π 3, where n is an integer. secxcscx = 2cscx. Hence, considering cscx ≠ 0, secx = 2. and so x = ± π 3 - note that csc(± π …
