TS EAMCET 2017 Code A Solved Paper

Write the parametric equations of given circle
x=12‌cos‌θ
y=12‌sin‌θ
The coordinates of point A are given by,
x=12‌cos‌‌

π

3

=6
y=12‌sin‌‌

π

3

=6√3
The point A is (6,6√3)
The coordinates of point B are given by
x=12‌cos‌‌

π

6

=6√3
y=12‌sin‌‌

π

=6
The length of the coordinate is calculated as
AB=√(6√3−6)2+(6−6√3)2
=√2×62(√3−1)2
=6√2(√3−1)
=6(√6−√2)
