what is the csc5400

Answer 1

Is 5400 in rad or degrees?

Answer 2

im not sure it asks to find the exact value of csc5400

Answer 3

i know that 5400/15=360, so am i looking for csc360 or csc0??

Answer 4

Usually, if degrees are not given, it means the number is in rads. However, it the number of big, such as 5500, that usually means degrees to me

Answer 5

ok then its probably degrees

Answer 6

csc(5400 degrees) = undefined, just as csc(360 degrees) is also

Answer 7

oh ok so is any trig function of 360 degrees undefined?

Answer 8

No.
sin(360 degrees) = 0
cos(360 degrees) = 1
tan(360 degrees) = 0

csc is undefined because csc is 1/sin. 1/0 is undefined

Answer 9

how come 1/0 isnt 1?

Answer 10

You cannot divide by 0, it is a basic rule of math. If you do, you are basically destroying reality and get sucked up in a black hole or something :)
