Prove that:
Monica [59]

Recall that

sin²(<em>x</em>) = (1 - cos(2<em>x</em>))/2

so that

sin²(7<em>π</em>/8) = (1 - cos(7<em>π</em>/4))/2

sin²(5<em>π</em>/8) = (1 - cos(5<em>π</em>/4))/2

Then

sin²(7<em>π</em>/8) + sin²(5<em>π</em>/8) = (1 - cos(7<em>π</em>/4) + 1 - cos(5<em>π</em>/4))/2

… = 1 - 1/2 (cos(7<em>π</em>/4) + cos(5<em>π</em>/4))

… = 1 - 1/2 (1/√2 - 1/√2)

… = 1

What actual floor number do each student live on? Show your work also.
Ugo [173]

Heathe lives halfway up: 42 / 2 = 21st floor.

Raveen = 42 x 4/7 = 168/7 = 24th floor.

Alveera = 42 x 3/14 = 126/14 = 9th floor.

Rafi = 42 x 4/6 = 168/6 = 28th floor.

Suha = 28-24 = 4 /2 = 2 = 24+2 = 26th floor.

Arabi = 42 x 2/3 = 84/3 = 28th floor
