Answer to sets???

 

[Ram97]

I remember 2 things
-Main kisee ka anwer 270 likh k ayya hoon
-kisee aik sawal kee range 0-360 thee, 100% confirm

Agay khud sherlock ho sarey

As long as I remember there was 270 in the first part and then it was rejected....

 

[Ram97]

What abt sets???

 

[Dark Destination]

Trigonometry ka qs. where it was given cos^2 y - siny = 1

I wrote all three answers. Will i lose mark for not stating ''rejected'' for 270?

Was this part one or part two?

look man the first was tan one it had 0, 180, 103.1 its range was 0-180
second was that cos one, its range was 0-360
why you worry ?

third was the radian which was totally different

First one wasn't tan one.

It was --> cos^2 y - siny = 1

How is this tan?

I must have mixed them :/

30,150, 270 maybe.

But if we write an answer outside the range, along with the other ones, will a mark be cut?

Because i am providing the answers the examiner requires, just didn't write ''Rejected'' with the one outside the range.

you sure its outta range?

 

[Dark Destination]

you sure its outta range?

Yes, if it is. Not writing ''Rejected'' leads to a loss of a mark or not?

 

[Faizan Muhammmad]

Yes, if it is. Not writing ''Rejected'' leads to a loss of a mark or not?

I think it would :/

 

[Dark Destination]

I think it would :/

Won't the examiner just ignore it? Because the required answer is there. ._.

 

[M.Omar]

yup coz penalise for xtra sol as indicated in start of MS :/
Wait was the first part abt tan or sin^2 sth pls tell...i think i can piece this all together based on this answer

 

[Faizan Muhammmad]

yeah but IF the range was given THEN we ignored it and THEN it does qualify as a mistake
the range is there for some reason

What? Where does it say about extra solution? :/

 

[M.Omar]

What? Where does it say about extra solution? :/

in the strt where they detail abt meaning of M1 and B2 e.t.c

 

[Dark Destination]

yeah but IF the range was given THEN we ignored it and THEN it does qualify as a mistake

But the required answer is there In the working space. It is present in the space.. and the examiner will see it. And the requirement of the question will be fulfilled.

You are saying, the examiner is going to cut a mark for something extra?
Even though i solved all the steps. did the question perfectly, just didn't write ''rejected''?

look one's range was 0-180 anothers 0-360, I am damn sure
since for tan we have 3 values within 0-180 so it must be that one
the sin2 one must be the one with 0-360
