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:
