Radian measure [Circular system] - A radian is the measure of an angle at the centre of a circle subtended by an arc, whose arc length is equal to the radius of the circle..Measurement of Angles
To measure an angle we shall use two kinds of units, the degree unit and the radian unit. A degree(Sexagesimal system) is defined to be an angle formed by half-line (or a ray) rotated about its end point (1/360) of a complete revolution. Types of Angl..
Proof:
Let PQR be a circle with centre O and radius r. Consider an arc AB of the circle whose length is equal to radius of the circle. Draw OA and OB and Produce AO to cut the circle at C. Angle at the centre is proportional to the length of the corresponding arc..

All the solutions that these tutors give are correct I got a 83% on my last quiz, Thank you so much - Giara
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
Tutor made sure i understood all points by asking if they were clear. Good job tutor thanks Tutorvista.
I have browsed many mathematics sites. But this one is the best. It focuses on the important points and leaves out the unimportant ones. The summaries are great for memorising things in a fast way.
