Calculating Trigonometric Functions in the Cylinder System

[Jerina]

i got to find the sin and cos of cylinder. in the cylinder system please help me

your question is not clear jerina.

i got to find the Cylindrical coordinates :s sorry

 

[nkks]

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, \vartheta, 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, \vartheta, z) on this cylinder will have an r value of a.

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

you should show some sincere work before you ask anyone for help.
