csc(50^o) = 1.305407

Explanation:

This is one of those times when you need a calculator with trig functions (or some equivalent technology).

When I evaluated this, I used Excel
[1] which does not support arguments in degrees
color(white)("XXXX")so I had to convert 50^o into radians
color(white)("XXXX")using 50 *(PI())/180 to get radians

[2]and which does not support the csc (cosecant) function
color(white)("XXXX")so I had to use 1/sin(theta) = csc(theta)

You might get lucky and have a calculator that works in both radians and degrees, and has a csc function; otherwise you will need to use one of the "tricks" above.
