Ok when your plotting a graph of Sin angle i against Sin angle r , which of those goes on the y axix ??

To determine which variable goes on the y-axis when plotting a graph of sin(angle i) against sin(angle r), we need to first understand the concept of independent and dependent variables.

In this case, sin(angle i) and sin(angle r) are both trigonometric functions, and the choice of which variable to put on the y-axis will depend on the relationship you are trying to visualize.

If you are interested in comparing the value of sin(angle i) to sin(angle r), where the value of sin(angle i) is the independent variable and sin(angle r) is the dependent variable, then sin(angle r) would be plotted on the y-axis. This is because the value of sin(angle r) depends on the value of sin(angle i).

On the other hand, if you are interested in comparing the value of sin(angle r) to sin(angle i), where the value of sin(angle r) is the independent variable and sin(angle i) is the dependent variable, then sin(angle i) would be plotted on the y-axis. This is because the value of sin(angle i) depends on the value of sin(angle r).

Therefore, depending on the relationship you are investigating, you will either plot sin(angle r) or sin(angle i) on the y-axis.
