The question gives us a graph for f(x), where f(x) = sin x.
It says that we have to sketch the graph of g(x) where g(x) = 1-sinx
how do u do that???
and besides this how do we do questions similar to this like
sketch the graph of f(kx), f(x) + k , kf(x) and all when the graph for f(x) and the value of k are given to us???
plsssss help.....asap!!!!!!!!! :-[ :-[
thanks in advance!!!!!! :) :)

2 questions plz.
1) Could u plz provide me with a past paper question. year/paper no./ etc.
2) What is the scale of the x-axis in the sinx curve. is it in radians or degree?
-
hmmmm..
its not a past paper question....its in one of my ref books
and for the scale...its degrees

k..cool..will answer in my next post..
-
hmm...kkk
m waiting dude!!!

k first make the table for f(x) = sin x (x = 0,90,180,270,360)
next make the table for g(x) = 1-sin x (x=0,90,180,270,360)
u can use the f(x) values in g(x) like this g(x) = 1- f(x)
--
after having the table ready ..plot them..
the final graph should look somehing like the 2nd image
-
the final graph should look something like this

hmmmm..
its not a past paper question....its in one of my ref books
and for the scale...its degrees
uhm...which book??
-
thanks adi...i really appreciate this....
@priyu i have this book form David Rayner nd its called " General mathematics, Revision and Practice "
hey adi cud u plss answer my other question as well....
PS for every single question will we have to make a table and plot the graph...even when it just tells us to sketch....there must be some shorthand method....

making tables is ot a tedious task..it looks a little complicated thats it...like i said .. u can see and understand the questoin..like here...u can use one function in the other to make it easy.!!
@priyu - yes..i'm giving it..
-
ohhk i get that,...bt i remember reading in some book about the transformations of these graphhs.....i'll get back to u wen wd it in my next post....
@priyu m giving paper 5....i wish i cud paper 6 toooo...its too easy.....bt our school doesnt give us this option!!
-
So, how and wat hv u done for chem??

where r u from???which school???
-
The minus means turn it upside down and the one means move up one

lol...no
me as in @d!_†oX!©...m doing ppr 5
nd he as in AM is doing ppr 6
-
the final graph should look something like this
@ | am | - wat software did u use 4 making the graph...
-
i remember him saying some microsoft software
really good rite??
i guess aadi uses some ms math or something i really dont know
