Do we need to convert the system of calculator to red in like this queation

AI Thread Summary
The discussion centers on whether calculators should be set to radians for trigonometric functions. It is clarified that when angles are not specified in degrees, arguments should be considered in radians. The mention of "red" appears to be a misunderstanding, as the correct term is "rad." Users agree that setting the calculator to radians is necessary for accurate calculations in such cases. Overall, using radians is essential when dealing with trigonometric problems lacking degree specifications.

Sorry I don't understand what you mean.
 
In the ( calculator ) there are many systyem for exampl when you press MODE button in calculator you can chose ( Deg ) or ( Rad ) or ( Gra )

my queation now do we need to change the system of calculator to rad in like above question
 
Yes, you do.
 
In any problem where you do not specifically have angles given in degrees, you should think of arguments of trig functions as being in radians.

(You had said "in red" before rather than "in rad"!)
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
