question is that reflect (3,4) firstly on x-axis then on line y=4. plz answer this

cmon dont fret its easy
for the ques, reflecting in a particular line means that line is ur mirror and like any light question of physics u always shud remember this that image distance from the mirror = object distance from mirror so here if we first reflect it in x axis we will get same x coordinate 3 and 4 will go to -4 so coordinates now are (3,-4) now we go to line y=4 now u see that reflecting in any y line the x coordinate remains same always this is also true for a y coordinate in reflection in any x line like x=4 !
so coming back to ques now 3,-4 goes to (3,12) ! plot the point on a normal sketch and u shud get the hang of this !

Well, I'm not aware of any books that explain every topic clearly so it depends on you're teacher, I think. Just listen to what your teacher is explaining, and ask every single thing which you don't understand. Also, practice topical past papers while doing chapters, etc. Do this right now because delaying it will just make things worse.

New Additional Mathematics by Ho Soo Thong and Khor Nyak Hiong.

Use this book. It's the best there is. And yeah Add Maths is the most frightening subject in O level. But once you get what your doing it becomes more fun then it's worth.
