I have no clue about it........

a) g(x)= max(sin Î t) in t=0 to 2.

= max (sin m) mε[0,2Π]

this is at m=pi/2 .

i dunno wat can be its graph... [12]

a point? .. (pi/4 , 1)

I too dont know anything about it........but keep trying....and reply when u have got it..........

for first one :

for third one :

now, are these graphs correct

do correct me if something is wrong :)
