[robust vigil]

[next urchin]

how in the world will u do this

[hexed crest]

its the same equation as before

x = sinfeta

[next urchin]

can you explain

[hexed crest]

explain what

[next urchin]

the second one

i don't get it

[hexed crest]

i just told

let sinfeta = x

[next urchin]

bro i am so confused

if i let sintheta = x

do i put sin theta into the function

[hexed crest]

what

if u do that sub the equation in part ii becomes the equation in part i

or are you stuck on part i

[next urchin]

part one gives u 0

but part 2 is what makes no sense

[hexed crest]

so do that sub

then you get the equation in part i

then solve that

find what x is

then sub sinfeta back in

[next urchin]

SUB IT INTO WAHT

OK
