I don't know what an "eqation" is and if you meant "equation" that doesn't make any sense either since there is no equals sign anywhere to be seen. Now if what you really want is the value of the cosecant function at 
, that is another story.
The cosecant function is the reciprocal of the sine function. is in the 4th quadrant where sine is negative. It is also equal to 
.
Use the unit circle:
to find the value of )
Remembering that the sine is the y-coordinate on the unit circle. Then just take the reciprocal and rationalize your new denominator.
By the way, "pie" is a prepared food item, "pi" is the ratio of a circle circumference to its diameter.
