On which interval are both the sine and cosine functions increasing? a) (3pi/2, 2pi)
b) (pi/2,pi)
c) (0,pi)
d) (pi,3pi/2)

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

answer4 to the second power is 16

and 4 to the third power is 64,
