00:01 Okay, so sign of negative pi over 3.
00:05 Sign is an odd function, so this is equal to negative sine of pi over 3.
00:11 Sign of pi over 3 is root 3 over 2 using our unit circle, so this is negative root 3 over 2.
00:22 Seekint of negative pi over 3.
00:25 Secant is 1 over cosine, so this is 1 over cosine of negative pi over 3.
00:31 Cosine is an even function...
