unfortunately there wasntXayma said:Was there any diagram that came with this? Im intrigued by "lower trapezia"
I dont think I give the answer for the polynomial Qwithoutaface said:by inspection only works if they don't give you the answer
lol u asked, so here it ismojako said:solve 6x^4 - 7x^3 - 28x^2 +35x -10 = 0
ROFL i didnt even bother with thatmojako said:since the coefficients of the polynomial are all integers, the numerator of any rational roots is a factor of the constant term, and the denominator is a factor of the leading coefficient.
BTW do we have to know this?? It's not mentioned in the syllabus, which however has a section (section 7.1) which specifically talks about integer roots being factors of the constant term. I've seen a question like this but I thought it was a bad question.
Now that you secret inspection procedure has been broken, would be very friendly to do the circle question not by inspection?
thx, its corrected.CrashOveride said:You mean E is to the right of P on the tangent...then all works well thanks for that Archman ^_^

You fuck around with a few things in your head until you find one that works.mojako said:omg.. inspection..
its such a wonderful and powerful technique..
I wonder why we weren't taught that technique at school
On the serious side, how do these things come to your mind?
