36 minutes is equivalent to a fraction of an hour

36 minutes is equivalent to a fraction of an hour

How many hours is 40 minutes

2 / 3

40 minutes is the same as less hours?

40 minutes = 2 / 3 hours

Is there such a formula for sin & # 178; a = Tan & # 178; a / 1 Tan & # 178; a?

Yes, it should be sin & # 178; a = Tan & # 178; a / (1 + Tan & # 178; a)
thank you
In addition, tan2a = 2tana / (1-tan & #178; a)

If the square of | X-2 | + (y + 1) = 0, find the cube of (x / y)

If the square of | X-2 | + (y + 1) = 0
So X-2 = 0, y + 1 = 0
So x = 2, y = - 1
So the cube of (x / y) = (- 2) = - 8
If you don't understand, I wish you a happy study!

The cube of (x + Y / 2x × y) is much more simplified than the square of (X-Y / X × y) and (X-Y / X × y) respectively

(x + y parts of 2x × y Square) of the cube (x square - y parts of X × y cube) of the square [2 (X-Y) parts of 1]
=(2xy^2)^3/(x+y)^3*(x^2-y^2)^2/(xy^3)^2*2^2(x-y)^2
=32x(x-y)^4/(x+y)

1 and 2 / 3 - {5 and 3 / 4-2-2-2-2-2-2-2-2} [(- 1 / 2) square + 3 times (- 3 / 4)] times 1 / 2 cube}

1 and 3 / 2 - {5 and 4 / 3-2 ｛ 178; - 2's Square △ [(- 1 / 2) square + 3 times (- 3 / 4)] times 1 / 2's cube} = 5 / 3 - [23 / 4-4-4 ｛ (1 / 4-3x3 / 4) X1 / 8] = 5 / 3 - (23 / 4-4 + 1 / 2 ｛ 2) = 5 / 3 - (39 / 4 + 1 / 4) = 5 / 3-10 = - 25 / 3

-The square of 2 is multiplied by the square of 2 and 1 / 4 + (- 3 / 2) divided by the cube of (- 1 / 2)

Original formula = - 4 × 9 / 4 + 9 / 4 △ (- 1 / 8)
=-9-9/4×8
=-9-18
=-27

When a = - 1 / 3, the cube of a + the absolute value of 1 + the cube of (a + 1)=

A ^ 3 = - 1 / 27, so the absolute value of cube + 1 of a = 26 / 27, and the cube of a + 1 = (2 / 3) ^ 3 = 8 / 27
So cube of a + absolute value of 1 + (cube of a + 1) = 26 / 27 + 8 / 27 = 34 / 27
