#### Topic: Radian vs 360-degrees

I have set the trigonometry to use degrees instead of radian.

When I make user defined functions and constants like the following

K = 16

V1 = cos (K)

F1(t) = cos (t)

F2(t) = cos (t)*cos(K)

F3(t) = cos (t+K)

Then V1 is calculated as radian - disregarding the trigonometyr setting!

The F1 works with degrees - as expected.

For sure the F3 also works with degrees.

But what about F2?

Why can not all cos/sin/tan be in degrees?
