<p>^ the point was (-1, -pi/4) right? how would you graph this on the calculator? I’ve never tried using a calculator for this kind of problem before lol</p>
<p>to the polar question you can count; if the magntiude coordinate is 1 start from the polar axis, if it’s negative start on what would be the -x axis for a rect. coord sys;; and for each pi/4 count 45degs counter-clock if it’s positive and clockw if it’s negative…</p>
<p>i haven’t seemed to find the question in the thread yet: it was x^2- 7x +2 with roots p and q and it asked for the question for the roots of p+1 and q+1 , did you guys get
x^2 - 9x +10 ??</p>
<p>I should have used my ti-89 for more of the problems but I didn’t. I got 1-30 right for sure but as I did 31-40 I began to struggle and ended up leaving 9 blank and getting probably 4 wrong.</p>
<p>I completely missed the dog question, the small triangle with the big triangle, and the acute triangle with heron’s formula. For the last problem (50), did anyone apply differentiation? :D</p>
<p>Also, did anyone use any ti-89 shortcuts, such as to find the 11/29 answer?</p>
<p>Oh, and I was stumped by the medicine dosage intake question. I know you had to set the .25 to the 4th power or something but my mind went out completely. I think I’ll just retake the test =X.</p>
<p>There was the question about some football teams or something and how many teams were there if every team played each other once.
Was the answer 8 teams? </p>
<p>I remember there being a question in the barron’s book that was almost exactly the same question except it asked for how many people were in the room if … handshakes were exchanged.</p>
<p>ahh i should have omitted instead of guessed…T_T I guessed 1 or 2 wrong…so now I have 3 definite wrong answers, maybe 1 or 2 silly mistakes…hmmm wonder what that’ll bring me to</p>
