I'm working through some examples in a text book but i am unable to get the desired answer on my calculator, i keep getting math error and various other results which are not the answer i'm looking for. What i have is: √ 62.9∠88.2 / 0.00165∠72.3 Please could someone tell me what answer you get and i'll see if it matches what i have in my text book. If it does i'd be interested to know exactly how you entered it into the calculator. If the above isnt clear it's the sq root of 62.9∠88.2 / 0.00165∠72.3. Thanks.
