Hi Esu_chan, I had to face a similar decision to you back when I was doing my HSC. If you're doing poorly in Mathematics then I suggest you either take the advice given to you above or you can take your career advisor's advice and drop down to General. I did general maths when 2U was proving to...

Yes, my apologies, I forgot to write the minus sign.

Yeah thanks I got it. I solved for sin(x)=0 and tan(x)=1 and got the 5 solutions -pi, 0, pi, pi/4 and 3pi/4.

Hi everyone, The problem I have is find all solutions for: sin(x)tan(x)=sin(x) on the interval -pi<=x<=pi I suck at solving these kinds of problems in general. If anyone knows of some great websites or videos which have a good explaination for solving trig functions please post them here...

I've given the 2nd one a shot by just expanding 1 side but to be honest with you this one has me stuck. Spiralflex's method is best method I know of if expanding then rearranging and factoring fails.
