Calculating Trigonometric Functions in the Cylinder System

In summary, the conversation is about finding the cylindrical coordinates for a cylinder, but the details of the cylinder are not provided. The equation for the cylindrical coordinates for a vertical cylinder is r = a, where a is the radius of the cylinder. The conversation also mentions the use of spherical coordinates, but it is not clear how they are related to the problem at hand. The speaker also advises to show some effort in solving the problem before asking for help.

i got to find the Cylindrical coordinates :s sorry
 
  • #4
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.

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

FAQ: Calculating Trigonometric Functions in the Cylinder System

How do I convert between the Cartesian and Cylinder coordinate systems?

To convert between the Cartesian and Cylinder coordinate systems, you can use the following formulas:

  • x = r * cos(theta)
  • y = r * sin(theta)
  • z = z

where r is the distance from the origin to the point, theta is the angle from the x-axis to the point in the xy-plane, and z is the same in both coordinate systems.

What is the unit circle and how does it relate to the cylinder system?

The unit circle is a circle with a radius of 1 centered at the origin. In the cylinder system, the unit circle is represented by the circle with a radius of 1 in the xy-plane. The angle theta in the cylinder system is equivalent to the angle in the unit circle, making it a useful tool for understanding and calculating trigonometric functions in the cylinder system.

How do I calculate the trigonometric functions in the cylinder system?

To calculate the trigonometric functions (sin, cos, tan, cosec, sec, cot) in the cylinder system, you can use the following formulas:

  • sin(theta) = y/r
  • cos(theta) = x/r
  • tan(theta) = y/x
  • cosec(theta) = r/y
  • sec(theta) = r/x
  • cot(theta) = x/y

where r is the distance from the origin to the point and theta is the angle from the x-axis to the point in the xy-plane.

Why is the cylinder system useful for calculating trigonometric functions?

The cylinder system is useful for calculating trigonometric functions because it allows for a simpler representation of 3-dimensional space. By converting coordinates to the cylinder system, the problem can be reduced to a 2-dimensional space, making it easier to visualize and calculate trigonometric functions.

How can I use the cylinder system in practical applications?

The cylinder system is commonly used in engineering, physics, and other fields to represent and analyze 3-dimensional objects and systems. It can be used to calculate forces, angles, and distances in various scenarios, such as calculating the trajectory of a projectile or determining the height of a building.
