I got the same, and the other value for y i got was 1/2, i believe.

yes and the other y i got was 1/2

first of all the other value was .5 and does anybody remember question 13 on the test and the the answer

will i get it wrong if i listed the answers like (x,y) and (x,y) instead of doing (x,x) and (y,y), i grouped the 2 related ones, fuarkk

and i got the sin75 one wrong and the 1/X^2 -6 f^-1(x), how did you do that one?

For the second last one, I got 17/81

@Jessica

For sin 75 .. It's sin (45+30)

look at reference sheet.. Formula is sinAcosB + cosAsinB

Plug all values in

Rad(2)/2 * rad(3)/2 + rad(2)/2 * (1/2)

rad(6)/4 + rad(2)/4

Rad (6) + rad (2) ////// 4

hey what was the answer to the sin75 question? i got something like (radical2 + radical6)/2... is that right?

Yeah! I got (-4.5, 0.5) and (0.5, 5.5). Do you remember the answer for the exact value of sin75??
