In summary, the conversation discusses how to find the coordinates on a diagram without a coordinate system. It is suggested to use a reference frame with X and Y axes and define a principal direction towards the given coordinates. The value of Z, which represents the radius of the inner circle, is also mentioned. This information is intended to help a friend create a tide simulation program.

Hey can someone tell me how to find the co-ordinates on this diagram.

Actually, no, because there is no coordinate system!


Do you intend to have a coordinate system with x and y axes horizontal and vertical?

Assuming that and that you are given coordinates (x,y) and (x2,y2) you can find the slope and equation of the line between them but you would still need to know the radius of the inner circle to find the coordinates of the point marked with a "?".

Without a reference frame, you can't find the coordinates. However, you can find the coordinates relative to X2,Y2 and X,Y.
If you let X2,Y2 be your origin, you can define your principal direction as being directed towards X,Y. Whether you create a unit vector in this direction or use some other length vector in this direction to define your reference, ? will just be some scalar multiple of your reference vector.
In other words, you can set it up so that if the value of X, Y, X2, Y2, and Z were later given, the coordinates of ? would naturally follow.

Hey in reply to the first post Z is the radius of the inner circle, and this was for a friend who is trying to make a program to simulate the tides.
 

FAQ: How to Find Co-ordinates on a Diagram for Simulating Tides?

What is a random co-ordinates question?

A random co-ordinates question is a type of question that involves randomly generating a set of coordinates and asking the participant to identify the location or perform a task related to those coordinates. It is commonly used in research studies and psychological experiments.

How are random co-ordinates questions designed?

Random co-ordinates questions are designed by using a computer program or a random number generator to generate a set of coordinates within a specific range. The coordinates can be in 2D or 3D space and can represent locations on a map or in a virtual environment.

What is the purpose of using random co-ordinates questions in research?

The purpose of using random co-ordinates questions in research is to eliminate any potential bias or influence on the participant's response. By randomly generating the coordinates, the researcher can ensure that the participant's response is based on their own cognitive abilities and not on any external factors.

How are random co-ordinates questions used in psychology experiments?

In psychology experiments, random co-ordinates questions are often used to assess spatial memory, attention, and problem-solving abilities. Participants may be asked to identify the location of a hidden object, navigate through a virtual environment, or complete a task at a specific set of coordinates.

What are the benefits of using random co-ordinates questions in research?

Using random co-ordinates questions in research can provide more reliable and valid results as it eliminates potential biases and allows for more controlled testing conditions. It also allows researchers to study cognitive abilities and spatial skills in a more objective and standardized manner.
