On a circular track with center at O, A starts at a point P and runs in clockwise direction. At the same time B starts at Q and runs in anti-clockwise direction the angle POQ measured in the clockwise direction is 270 degree. The distance covered by B by the time he meets A for the first time is equal to is equal to the distance covered by A between the first and the second meetings. What fraction of the track length does A cover by the first meeting?
A largest cylinder is cut from a solid cone of Radius R and height H.find the ratio of the Volumes of the cylinder and remaining part of the cone...
My main question is how to start these questions i face huge difficulty whenever this cutting is done in the question
is there a defined 2 solve these kinds of question then kindly share it
Please see attached file. Hopefully have not made any mistake, it has been years since I have done differentiation!

Edited: Bill and Clinton take the square of a certain decimal number and express it in base 5 and 6 respectively. Then Bush comes and he takes the two representations and assuming that the expressions are in base 10, adds the numbers. Which number/s from 0 to 9 cannot be the value of the unit's digit of the sum obtained?

Let
θ=inverse sin 7/25
Consider the sequence of values defined by
a n=sin(nθ) (this means a of n = a down n)
They satisfy the recurrence relation
a n+2=k1 * an+1+k0 * an , where n belongs to natural no.
(this means a down n+2 = k down 1 * a down n+1 + k down 0 * a down n
for some (fixed) real numbers
k1,k0
The sum
k1+k0 can be written as p/q, where p and q are positive coprime integers. What is the value of p+q ?👍

The remainder when 28! is divided by 62 is ...guys plz help..
The remainder when 28! is divided by 62 is ...guys plz help..
62 = 2*31
We find remainders individually by 2 and 31
28!Mod2 = 0
30!Mod31= -1 (Wilson's Thm)
30*29*28!Mod31 = 30
29*28!Mod31 = 1
(-2)28!Mod31 = 1 = 32
28!Mod31 = -16 = 15
So rem is of the form 2x = 31y + 15
Rem = 46
