    Hi r-soy! :smile:

    Q3: fine so far, except:​

    i] 5.8 isn't two decimal places

    ii] i don't get exactly 0.64

    iii] you still need to convert it into an angle before you subtract 180º :wink:

    Q4: 64 (= 26) is correct, but you seem to be using the fifth power of the (cos + isin) for some reason :confused:
