how to calculate to join using your calculator you were told by your lecturer to calculate to join from point A to point B you must always write the point we you are standing we you want to observe from we want to calculate the joint from you must write that in the first line point a and it's coordinates always write your y-coordinate first and then your x coordinate as this is standard in South Africa then you need to write down the coordinate for point B we are observing two you want to work out the direction and distance from point A to point B so B goes in the second line and you're right on its coordinate again who's the y then the X now you can draw a line this is just a standard format of writing it so that you do not make a mistake when you calculate your join now you have to use the button coordinate here - the top one for both x and y take the bottom coordinate and subtract it from the top coordinate on your calculator so you will type in seven five 0.1 one - two four eight zero point four three and then press T equals to sign after that he will store this value in a or b these little pink hazel beads on your calculator and I always say store your Y value in B's he goes shift store in B you can also write that value down negative one seven three oh come on three two it's also important to show your sign of your value that you have now you have to do the same for the x coordinate but this time we are going to store it in a so you take five eight to nine 9.80 - five six three 12.00 equals two that gives you a positive 1 9 8 7 comma 8 Oh store it in a in your calculator so you go chef store and a now the value is stored in a if you switch your calculator off by accident your value and you switch it back on again your values will still be stored in a and B so you say recall a there's your value recall B and the is your B value now we need to go on to the next part of the calculation we need to calculate the join from A to B for that we need to use our calculators we will use the function shift pole then we will say alpha a because we want the x coordinate first shift comma alpha B the y coordinate second in survey we always use our y coordinate first and our x coordinate second but our calculators are designed for maths we math sees using the x coordinate first and the y coordinate second that is why we put in the X versus and then the Y now you press your equals to sign and this will give you the answers on the screen first your distance then if you press this button here you'll see there comes the direction but nerd the direction has got a negative sign we have to do something to this negative direction to make it a positive direction the values is also stored on your calculator either in x and y or a 1/8 depending on which model of casio calculator you are using so you can press the Clear button in say Rico eggs there is your distance and and recall why and you will write down the direction but in this case we need to change this direction the direction here we will have to say equals to then that value is stored in your calculators memory - for use then you will say plus 360 degrees and it will give you a new direction now you will have to press this little button over there and it will put it to you in degrees minutes and seconds so we never write decimal seconds either the standard format for writing your answers and giving your answers in an exam paper is join A to B and then you will give the distance 2 6 3 5 comma 404 and in your direction in degrees minutes and seconds and that is your final answer you will always be able to check your answer by doing a polar from a B to A or A to B
