Could someone check my work

This is for Trig and it's inverse trig functions. I just need someone to check if I got the exact values correct.

Is the Arcsec2= 60 degrees?

Arcsin squareroot of 2/2=45 degrees?

Arccot 1/squareroot of 3=60 degress?

Arctan (-squareroot of 3)= -60 degrees?

Sin (arcsec(-25/7)) = 24/-25?

-
all but the last ...sine is > 0 in the 2nd quadrant
