They are both the same because anything times 0 equal 0 and 0+0 equals 0.
The following are reciprocals...
sin and csc
cos and sec
tan and cot
Set each binomial equal to zero to solve.
2n + 3 = 0
2n = - 3
n = - 3 / 2
n - 4 = 0
n = 4
So n = -3/2, 4
The answer is 28. My answer is correct. 7, 14& 21 can't be the LCM son the answer should be 28.
