tan(pi/4)=1
tan(pi^2/4^2) = 0.709...
tan(pi^2/4^2) = 0.709...

Original post by mqb2766
tan(pi/4)=1
tan(pi^2/4^2) = 0.709...
tan(pi^2/4^2) = 0.709...
But the q says that x=tan^2 y
So I subbed y into here
X=tan(pi/4)^2

You did
tan((pi/4)^2)
so you squared pi/4 to get pi^2/4^2 and callculated tan of that. The question says
(tan(pi/4))^2
so square the result of tan(pi/4) which is 1.
