i got to find the sin and cos of cylinder. in the cylinder system please help me
 
Physics news on Phys.org
I'm sorry,I think it deals with higher mathematical trigonometry.I know few about sin & cos but like sinx & cosx and there calculation like how to find the reasonable range of x ;in sinx+cosx=sin2x

I'm guessing that you need to find the cylindrical coordinates for a cylinder, but you haven't told us anything about the cylinder you're working with. A point in cylindrical coordinates is an ordered triple of numbers, (r, [tex]\vartheta[/tex], z).

For a vertical cylinder of radius a whose center axis lies along the z-axis, the equation is very simple: r = a. Every point (r, [tex]\vartheta[/tex], z) on this cylinder will have an r value of a.

Like the first one. The second one shows spherical coordinates.
