In geometry, given a triangle ABC and a point P on its circumcircle, the three closest points to P on lines AB, AC, and BC are collinear. The line through these points is the Simson line of P, named for Robert Simson. The concept was first published, however, by William Wallace in 1799

If xy+x+y=2020
find x and y.
Sol:
xy+x+y=2020
1+x+y+xy=2021
(1+x)(1+y)=43*47
So. 1+x=43. and. 1+y=47
x=42 and y=46

A= -------------------------- Then
(36)^⅓+(6)^⅓+1
find (A+1)
Solution :
5= 6-1
=[(6)^⅓]³ -1
=[(6)^⅓ -1] [(6)^⅔+(6)^⅓+1]
5
------------------ =[(6)^⅓ -1]
[(6)^⅔+(6)⅓+1]
So. A= [(6)^⅓ -1]
A+1 =(6)^⅓
(A+1) =(6)^⅓
(A+1)³ =6
A.P. व G.P.के अलावा H.P. भी होती है।
A.P. के पदो को उल्टा करके लिखे तो H.P. बन जाएगी।
किसी AP का mवां पद nहै।
और nवां पद m है।
तो बताओ m+n वां पद क्या होगा।
