holy shit i thought sin had 2 answers and tan had 1 (still 3). thank you based multiple choicetanx -2 has 2 solutions in 2nd and 4th quadrant while sinx only has one answer pi/2 therefore 3
10/10, state rank right here.a

hrrm, maybe... what about the other 90 marks?10/10, state rank right here.
There are actually only 2 solutions, since when you sub pi/2 into the equation, you get no solution. This is because tan(pi/2) does not exist (sub tan(pi/2) in your calculator and you will get math error).tanx -2 has 2 solutions in 2nd and 4th quadrant while sinx only has one answer pi/2 therefore 3
you get the pi/2 from the (sinx - 1) bracket, but in the end it doesnt matter since its undefined in the tan curveWhy do you need to tan (pi/2)? It was just inverse tan -2, which has two solutions
plus 1 solution for sine (pi/2)
Tan(pi/2) is undefined though, the tan curve
9/10 my streak has endedThere are actually only 2 solutions, since when you sub pi/2 into the equation, you get no solution. This is because tan(pi/2) does not exist (sub tan(pi/2) in your calculator and you will get math error).
But wolfram alpha says 3 solutions. If not, draw the diagram between 0 and 2pie and you will see 3 roots.9/10 my streak has ended
funny story, I originally thought tan had no solutions and sin had 2 so b was going to be my answer. and i realise i'm wrong with both my assumptions
yis im gud at meth
I drew the diagram :/But wolfram alpha says 3 solutions. If not, draw the diagram between 0 and 2pie and you will see 3 roots.
meth is messing with meBut wolfram alpha says 3 solutions. If not, draw the diagram between 0 and 2pie and you will see 3 roots.
well if you were to draw the graph you'll plug in pi/2, you get an undefined y value. therefore i presumed those straight line sections are in fact asymptotes. therefore thats why i put 2 solutions.... quite worried for this as it is one of the two marks that are ambiguous with me.But wolfram alpha says 3 solutions. If not, draw the diagram between 0 and 2pie and you will see 3 roots.
5 is definitely B, 7 is the one im worried boutSome ppl got D for q5
XD
And everyone argues about q7 :/

If 7 is C then i lost 2 marks for MC5 is definitely B, 7 is the one im worried bout
problem is it all rides on this one and another answer (depending if they can read my writing) that will determine if i get 97-98 or 98-99, hopefully 7 is b and im in a real chance to get state rankIf 7 is C then i lost 2 marks for MC
if 7 is B then GG another mark gone :/

The picture clearly shows 3 x intercepts, between 0 and 2pie, hence 3 solutions.well if you were to draw the graph you'll plug in pi/2, you get an undefined y value. therefore i presumed those straight line sections are in fact asymptotes. therefore thats why i put 2 solutions.... quite worried for this as it is one of the two marks that are ambiguous with me.
No, there is a chance at pi/2 there is an open circle, hence B would be the answer in this case.for fuck sakes, i did not see that coming, that nails the bloody cover on the coffin, it must be 3...
i put 3 initially but then was like tanpi/2 is undefined, i freaking hate multiple choice now.
