Paper 12.
Question 11,How do solve the whole thing I dont get it

[elemis]

Okay. Hang on.

[elemis]

(i) 4-3sinx = 2

Hence, 4-2=3sinx  I re-arranged the equation

2/3 = sinx 

sin^-1 2/3 = 41.8, 138.2 degrees

Converting to radians gives: 0.730 and 2.41 respectively.

[elemis]

(ii) Basically you reflect a regular sine graph in the x axis. Then multiply each Y coordinate by 3.

After that vertically move the graph by 4 units.

[elemis]

(iii)

Basically they are asking you to find the range of y coordinates for which the Sine Graph has no x values.

Looking at my picture we can see that the graph has no point below the y coordinate of 1 or above the y coordinate of 7.

Hence k > 7 , k < 1

[elemis]

I dont know the others

[Freaked12]

Ah we meet again Lioness 

If a function is to have inverse,it must be one - one function.The graph of such function can only be crossed by a line parallel to the x axis once only .

As our Lioness Ari drew in his Graph the highest value by  which the graph is parallel to x axis is 3/2 pi

Subconsciously you know I am a male. Your just a scatter brain.

[Freaked12]

Sub consciously or consciously I Doubt you are a Lion at all.

Maybe a Cub but thats about it.

Meet the Rogue Lion that will in time kill the heard's leader and finish off the cubs. 

I am so Jobless today 

[Aadeez || Zafar]

u both can just stop fighting with arguments as ur wepons

You sound drunk...

[Freaked12]

Give +rep to me yeah.i am dieing to get a rep

[Aadeez || Zafar]

rep r not asked for
they r given if any users want
so dont force them to give +rep

[nid404]

Give +rep to me yeah.i am dieing to get a rep

Do not ask for rep...against the rules
