can you solve a Q for me? ummm its from june 2005 C2 Q no: 4 b)

 

[Aahmsil]

I have attached a photo which shows how I solved it.
If you find the working to be intangible or still have a question, do feel free to ask.

man check this .. i have no idea how the hell is it solved
log3(x-2) = -1 ??

 

[Aahmsil]

Remember logxY=Z is the same as x^Z = Y
I've attached the working.

This is a question I thoroughly enjoyed solving.
It's really quite simple once you understand but until then, it's a downright bummer.
This is strictly the working, if you don't get it, tell me which part and I'll get back to you.

but man where the triangle from ???
-.-
nd sin is o/h

 

[DANGERBP]

MAN !! wake uppp !!!
i got the triangle .. but the sine thin ?? it shoud b opposit over hypotonis ???
nd after we get that how do we find the area of the circle !!

 

[Aahmsil]

This is how you get the triangle.
First divide the sector into two equal halves so Pie/3 becomes Pie/6
One side (the base) is the radius, r and the other side is 6-r.
In triangle COX, angle X is 90 degrees.
Check the figure of the sector.
OB is tangent to the circle C.
Radius is at right angles to the tangent.
Hence, trigonometry can be applied.
