The value at angle pie/4 and at -pie/4 is equal from y =3 ..therefore equatn of axis of symmetry y=3..i.e C=3

period or range for 1 cycle is 180..use 180/b...so b=1
amplitude i.e height from axis of symmetry in either directn so 5-3=2, 3-1=2..therefore a=2

I need help with this question, how can you find a?
Thanxx

a is the amplitude.

You get it just by comparing to the y = tan x curve.

tan x passes through the origin, it's passing at 3. So there has been a translation of 3. Therefore, c =3.

tan pie/4 = 1. But on the graph it's 5. You take 5 - 3 to get the amplitude. (y = 3 is the axis of curve here)
a = 2

 Yah, but nah. I meant just after or before me?  Both

[xlane]

Lol..oh dat...m usin cell..it got posted again..

[Alpha]

Ah no worries. 
I was getting bored... So, came in Maths thread.

[BlackBunny103]

Thanxx a lot both of you 

[Alpha]

Thanxx a lot both of you 

Most welcome. 
From both of us.

[xlane]

Thanks alpha ...ur are most welcum frm both of us

[Alpha]

Thanks alpha ...ur are most welcum frm both of us

LOL. 
Am honoured. 

[xlane]

lol...r u nw @ alpha

[jellybeans]

Heeeeeeelp.

if you rearrange for 6i) ;
isnt it 2t² - 9t - 5 = 0
(x-5)(2x+1) = 0
x = 5 or x = -1/2

why does the MS say (2x+1) => x = 1/2

help pleaaaase thankssss

! and for Q7iii) when are we supposed to use the "> or equal to " and ">" ? .... !!! THANKS

[xlane]

the mark scheme is wrng..i just solvd it nd it x=5 n x=-1/2...
