<p>not pi/2? thank goodness!</p>
<p>i dont remember a 0<x<pi</p>
<p>sccrscrub, was the restruction 0<x<pi or 0<x<pi/2 ?</p>
<p>does xx.25 round up to xx+1?</p>
<p>for example will 43.25 go to 44 = 800?</p>
<p>it cant be 0<x<pi/2, that wouldnt make it impossible, not undefined right?</p>
<p>it was 0<x<pi</p>
<p>so is that just useless information? or i guess it is periodic, but youd choose the one in the answer choices</p>
<p>@grojos. this is math not english. dont make this too hard to understand. impossible doesnt exist my math world. its usually does not exist. :D</p>
<p>im pretty sure it was 0<x<pi.</p>
<p>limit->infinity =750?</p>
<p>well what i meant was that there would be no value of x for which y=0 , or is “x not defined in the domain 0<x<pi/2” just a terminology question for me</p>
<p>if you want to get technical, undefined in math is the same as impossible</p>
<p>@anothergalaxy i got 750, but i dont remember the question</p>
<p>k so for the last one, how were you supposed to do it. i figured since two planes were parallel, the other one could be parallel to the two of them, and that’s the only one i said was true.</p>
<p>It was 0<x<π.
I remember because my process of solving it was typing the following into my calculator:
solve(ln(sin(x))=0,x)|0<x<π, which gave me x=π/2.
Then ln(π/2) = .45158</p>
<p>how was the last question worded, and what were the 3 options?</p>
<p>i think the last one asked “which one could be true?” and it said that two planes intersected one of the lines but the other plane did not intersect the line. as a result i concluded that the plane must be parallel to the line. i could be wrong but thats what i thought</p>
<p>I agree with that. what exactly were the 3 options? i remember 1 of them being true, maybe another but i dont remember what they were</p>
<p>The last question was I and III, I remember</p>
<p>it was pretty hard to visualise, i just thought of them aligned like an an asterisk *. what were I and III at least</p>
<p>sorry, the (x-a)(x-b)(x-c) was the one with 3 X-intercepts, not 3 y-intercepts lol</p>
