Question

please help

Answer 1

with what

Answer 2

if a>0 and b>0 and a+b= 1 . then prove that \[\left( a+1/a \right)^2 + (b+1/b)^2 \ge 12.5\]

Answer 3

well, i have a hint see if it works just substitute \[a= \sin^2\theta \] and \[b= \cos^2\theta \]

Answer 4

well substitute for those to and use trigonometry and then write a true statement if I am wrong then I would suggest to look it up

Answer 5

so is my answer right or not?

Answer 6

I don't really know if I'm correct or not but I thought it was that answer but I am not good at drawing and you wouldn't be able to actually read my drawing

Answer 7

I'm leaving, sorry :P

@Kainui is here :3

Answer 8

uhhh..

Answer 9

sin^4a+cos^a+sec^4a+csc^4a+4

Answer 10

tan^4a(cos^4a+4cot^a+csc^4a+cos^4a cot^4a+csc^4a cot^4a)
