<span>I have it, Watson !

<em>2 x (4 + 6 - 2) + (8/4)</em> .

-- The first parentheses encloses (4 + 6 - 2) and that's 8.

-- The fraction  8/4  is equal to  2 .

-- So now you have 2 x (8) + 2 .     That's 16 + 2 = 18</span> .

Here the order of operation is very important. I put few parenthesis to show you what is the correct result. First you have to multiply/divide, then u can add/subtract
(2*4)+(6-2)+\frac{8}{4}=8-4+2=6

What is the cofunction of cos 2pi/ 9
fiasKO [112]

The cofunction of cos is sin(90-x)

90 degrees is equal to PI/2

The cofunction becomes sin(PI/2 - 2PI/9)

Rewrite both fractions to have a common denominator:

PI/2 = 9PI/18

2PI/9 = 4PI/18

Now you have sin(9PI/18 - 4PI/18)

Simplify:

Sin(5PI/18)
