If a dart lands in the treble nine bed, the score is 9 x 3 = 27
tan(9) + tan(81) = sin(9)/cos(9) + sin(81)/cos(81)= {sin(9)*cos(81) + sin(81)*cos(9)} / {cos(9)*cos(81)} = 1/2*{sin(-72) + sin(90)} + 1/2*{sin(72) + sin(90)} / 1/2*{cos(-72) + cos(90)} = 1/2*{sin(-72) + 1 + sin(72) + 1} / 1/2*{cos(-72) + 0} = 2/cos(72) since sin(-72) = -sin(72), and cos(-72) = cos(72) . . . . . (A) Also tan(27) + tan(63) = sin(27)/cos(27) + sin(63)/cos(63) = {sin(27)*cos(63) + sin(63)*cos(27)} / {cos(27)*cos(63)} = 1/2*{sin(-36) + sin(90)} + 1/2*{sin(72) + sin(36)} / 1/2*{cos(-36) + cos(90)} = 1/2*{sin(-36) + 1 + sin(36) + 1} / 1/2*{cos(-36) + 0} = 2/cos(36) since sin(-36) = -sin(36), and cos(-36) = cos(36) . . . . . (B) Therefore, by (A) and (B), tan(9) - tan(27) - tan(63) + tan(81) = tan(9) + tan(81) - tan(27) - tan(63) = 2/cos(72) – 2/cos(36) = 2*{cos(36) – cos(72)} / {cos(72)*cos(36)} = 2*2*sin(54)*sin(18)/{cos(72)*cos(36)} . . . . . . . (C) But cos(72) = sin(90-72) = sin(18) so that sin(18)/cos(72) = 1 and cos(36) = sin(90-36) = sin(54) so that sin(54)/cos(36) = 1 and therefore from C, tan(9) – tan(27) – tan(63) + tan(81) = 2*2*1*1 = 4
An identity is true for all values of the variable whereas an equation is true for only a finite number of values.For example,Identity: (x + 2)3 = x3 + 6x2 + 12x + 27 is true, whatever the value of x.ButEquation: x3 - x = 0 is true only when x = -1, 0 or 1.

Yes, a 27 day cycle can change to a 35 day cycle. There are several factors that can contribute to a change in your menstrual cycle. Some of these include medication, stress, a change of lifestyle and certain medical conditions.
Oh God! A 30 day cycle? it's only supposed to last a week every month.
The typical menstrual cycle in "text book" terms is considered to be anything between 21 to 32 day cycle. yes that's normal
This depends on the length of your cycle. If you have a shorter cycle (less than 27 days) this is possible.

Between day 27 and day 1 of the menstrual cycle, if pregnancy does not occur, the uterine lining (endometrium) undergoes a process called menstruation. Hormonal changes lead to a decrease in progesterone, causing the blood vessels in the endometrium to constrict and the lining to break down. This results in the shedding of the lining and menstrual bleeding, marking the start of a new cycle.
I got my BFP on CD 31 of a 27 day cycle.
Between day 27 and day 1 of the menstrual cycle, if pregnancy does not occur, the uterine lining (endometrium) begins to break down and is shed. This process, called menstruation, involves hormonal changes that lead to the constriction of blood vessels in the lining, causing it to disintegrate and be expelled from the body. This shedding typically lasts for about 3 to 7 days, marking the start of a new menstrual cycle.
You may have conceived in February or March, depending on the regularity of your menstrual cycle.
