Official Math IIC January 2005

<p>oopsies youre right</p>

<p>if you do (x-(-2+3i))(x-(2+3i)) the i's dont cancel out so it does not make a quadratic function. i dont even remember what i put for that one</p>

<p>if a root is 1 + i, then other root is 1 - i, it was a u know it or u dun know it problem</p>

<p>do you know when we get our scores?</p>

<p>when an imaginary is a zero, so is its conjugate</p>

<p>heres the equation that 2-3i and 2+3i would be the roots for :
x^2-4x+13</p>

<p>yeah when do we get our scores? anybody know?</p>

<p>2 weeks i believe...</p>

<p>mannnnn do u guys remember any other problems?</p>

<p>no other hard ones. oh what did you ppl put for the logbase 2 (X^2+12X) one?</p>

<p>wat was the question</p>

<p>there was on problem with a triangle and it gave you three sides - sqrt 37, 3, 4 and it said what was sin C (angle between 3 and 4) i said .866</p>

<p>i put -16................</p>

<p>yeah...i said 0.866, too. Used law of cosines</p>

<p>yes that is correct (.866)</p>

<p>the one with the x^2 - y^2 = 72 was "-12"</p>

<p>there was also one about f(x) = 1/g(x) where does g(x)=0 i said 3 cuz there was a horizontal asymtote for f(x) there</p>

<p>yep, thats what I got (-12)</p>

<p>I also said 3 since there was a vertical asymptote</p>

<p>5 blank and 4 wrong for me so far haha. Hopefully still a chance for a low 700.</p>
