HI!!

OpenStudy (misty1212):

a triangle will do for the second one

OpenStudy (solomonzelman):

OpenStudy (misty1212):

arcsin(x) = A arccos(x) = B \[A+B=\frac{\pi}{2}\]

OpenStudy (misty1212):

@SolomonZelman sure hope so, then inverse of an any odd function is odd

OpenStudy (solomonzelman):

yes, the site is awful for me... I mean it is pretty bad on daily basis (before the update, but now it is even worse).

OpenStudy (solomonzelman):

Oh, I became green.... bye

OpenStudy (misty1212):
