i)The straight line connecting the points $1+i$ and $3-i$ where $1+i$ is the initial point and $3-i$ is the final point.
ii)The circular arc with the initial point $3+i$, final point $1+3i$ and centre $1+i$
Now I found these formulas in my notes that gave the equations for straight lines and circular arc and by putting the points into these I got this
However I have looked at some other examples and I am unsure as to whether this is correct.
Oh also my backslash button is broken so I someone could change the forward slashes to backslashes that would be greatly appreciated.
