Choose which of the following represents the volume V of a right circular cylinder as a function of its radius r , when the height of it is equal to its diameter d . => V = 2 π r 3 or V = π r 2 d or V = 2 π r or V = 2 π r 2..

The height h of a right circular cylinder is twice that of its radius r .Which of the following represents the surface area A as a function of its radius r ? => S = 6 π r 2 or S = 6 π r or S = 4 π r 2 or S = π r 2 6..

- Identical properties of circular functions and trigonometric functions. Let O be the origin. Let OA be the unit radius of the circle drawn with O as centre. Let OA trace an angle when OA takes the position OP. Then The tracing of the angle q and the arc AP = P( q ) a..

The following results have already been derived under Circular function..

(i) sin(A + B) sin(A - B) = sin 2 A - sin 2 B = cos 2 B - cos 2 A (ii) cos(A + B) cos(A - B) = cos 2 A - sin 2 B = cos 2 B - sin 2 A [The proofs of the above identities are same as for Circular functions..

When things are arranged in places along a line with first and last place, they form a linear permutation. So far we have dealt only with linear permutations. When things are arranged in places along a closed curve or a circle, in which any place may be regarded as the first or last place, th..
