Answer:
0
Step-by-step explanation:
cos(60) = ½
sec(60) = 2
sin(30) = ½
cosec(30) = 2
sin(0) = 0
2 - 2 - 0 = 0
With an expression like this, you have to raise all the terms to the 3rd power. So the 5 will become

,

will become

, the 4 will become

and finally, the

becomes

. If you place all of these together in the same fraction, the new answer equivalent to the initial expression is
Answer:
