Hey, really stuck on this question I dont even understand the information I'm given. I'll write down the question but if anyone has an edexcel C2 book it is p.84 q.10 as there is a diagram there.
"in the diagram OAB is a sector of a circle, centre O and radius R cm, and <AOB = 2 theta radians. A circle cantre C and radius r cm, touches the arc AB at T, and touches OA & OB at D and E respectively, as shown."
b) using triangle OCE, show that R sin theta = r(1 +sin theta)
Sorry its hard to understand when written out, but if you have the book the diagrams there. Any help would be muchly appreciated.
Thanks
