Why my Cosecant Plot different from the Textbook?

General Usage
1

Hi all,

I am trying to plot:

f(x) = 8csc(x) + 8csc(75-x)
plot(f, 0, 75)

But the plot is different from the textbook, can anyone explain why?

The problem is that your textbook assumes angles are expressed in degrees, whereas Julia assumes radians.

Julia supports degrees as well, but you need to use a special funciton name.Try this:

f(x) = 8cscd(x) + 8cscd(75-x)

Thanks a lot @mbaz , I just know about this!
