    Yes we can be asked. But more chances are that graph is drawn and you will need to write it's equation. Or equation and sketch of equation are given and you are required to fibd value of A or B points on graph. Such as point where y=2tan(X)-1 touches X-axis first time left of origin.

    It is at the end of syllabus. I have printed many sheets which are found everywhere in my bag and my table. But i rarely need it. But when you are doing further math or P3 you will need to look at it as a normal person does not learn all the formulas.

    Cos(x-1/4pi)=0 Cos is zero at 1/2pi or -1/2p so X-1/4pi=-1/2pi or 1/2pi x=-1/4pi or 3/4pi X=3/4pi can't be a solution as it is out of range. So x=-1/4pi

    i have not done S1. i will use my o level knowledge to do it. (i) if anyone wins the first one, the probability of the same person winning the game is clearly 1/2 (ii) there's only one way this can happen. the one who wins the first one loses the second and third. so it is 1/2 * 1/2 = 1/4 (iii)...
