with what

OpenStudy (cp9454):

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

OpenStudy (cp9454):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

so is my answer right or not? \

OpenStudy (anonymous):

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

OpenStudy (luigi0210):

I'm leaving, sorry :P @Kainui is here :3

OpenStudy (kainui):

uhhh..

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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