- Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with:
+close - Feel free to nominate the person for helper of the week in #helper-nominations
- Do not ping the mods, unless someone is breaking the rules. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
- If you're happy with the help you got here, and the server overall, you can contribute financially as well:

have you drawn a diagram?
i have considered the points as a and b
on the axes
ok
have you found point P
marble oyster
have you found point P
a,b
so you will need a line through P perpendicular to AB
yea
so slope of that line is -b/a
eq is like y/x-a= -b/a
so ay= -bx+ab
bx+ay-ab=0
length of perpendicular is c/2 too
c is?
the length of the diagonal..
why is the length of the perpendicular c/2
marble oyster
why is the length of the perpendicular c/2
diagonals in rectangle are equal
and they bisect eachother..right
marble oyster
diagonals in rectangle are equal
but they are not perpendicular
marble oyster
but they are not perpendicular
ok nvm im not getting anywhere
try finding the equation of the line through P perpendicular to AB
you can determine its gradient
marble oyster
try finding the equation of the line through P perpendicular to AB
i did
yb-ax=b^2-a^2
ok
now intersect that with line AB
yea
x+y= b+a - ab/b-a
is what i got
or wait
i got x = - b^2+ a^2/a^3
sorry i mean a^3/(a^2-b^2)
yb-ax = b^2-a^2
bx+ay = ab
marble oyster
sorry i mean a^3/(a^2-b^2)
were there brackets for this?
marble oyster
sorry i mean a^3/(a^2-b^2)
i don’t quite think that’s correct
yea
but i could be wrong
i wrote eqns wrog
;-;
what was your y value?
one se
c
marble oyster
yb-ax = b^2-a^2
bx+ay = ab
use these equations
b^3/(b^2+a^2)
x = a^3/(a^2 + b^2)
y = b^3/(a^2 + b^2)
would this seem accurate?
ok wow
ig i got it..
as a^2+b^2 = c^2
i dont get it
💀
marble oyster
x = a^3/(a^2 **+** b^2)
y = b^3/(a^2 + b^2)
would this seem accurate?
after i get this wht do i do? a^3/c^2 + b^3/c^2
marble oyster
after i get this wht do i do? a^3/c^2 + b^3/c^2
now calculate x^(2/3) + y^(2/3) and pray to a deity of your choice
marble oyster
now calculate x^(2/3) + y^(2/3) and pray to a deity of your choice
why lol
why the calculation or why the praying?
2nd.
the calculation is because you need to prove x^(2/3) + y^(2/3) = c^(2/3)
theres nothing complicated.,
the prayer is optional
damn u smort
as heck
thanks
