This is the last question i have for you because i got to college next week and will have my teacher supports and will not need yours
I would greatly appreciate if you can answer these questions. This will be all as you give the best answers. I really need this closure.
1)You know in trial and improvement when you do different trials with different values of x to see what value of x gives you a solution closest to the one given? Well do you write out all of the figures in the solution for each trial or do you round it?
2)I have a habit over rounding over 3d.p to 3d.p. is this okay and isit acceptable?
3)Write out all decimals for trials that have less than and up to 3d.p. so say the answer is 2.345 I'd write that down. Any trials above 3d.p I round to 3d.p. is this ok?
4)Would you put the (3d.p) next to it?
5)If I round a trial to say 3d.p I'd put "(to 3d.p)" next to the round trials? So like say when x=3.45 you get 34.45664567336 I'd write down 34.457. (to 3d.p). Will I lose marks for writing "(to 3d.p)" next to any rounded trial?
6)When finding angles using the invested fiction do you do the inverse curio. And the side ration in brackets like say you got
7)Cosx=a/h
Cosx= 5/8
X=cos−1 5/8. Or is it. X=cos-1(5/8)
Is it with or without he brackets. The marks schemes have without brackets but in all revision guides its with brackets and I do it with brackets. As a teacher should I put brackets or not
8)If I do put brackets will I lose marks
