| 00:0-1 | Hi , this is dr Pine recording from Tucson Arizona | |
| 00:03 | . We have a question from one of the students | |
| 00:05 | . Let's do a quick analysis and solve this one | |
| 00:08 | . To send your own questions , please subscribe our | |
| 00:11 | channel . Alright , so here's our analysis . Call | |
| 00:15 | sign A minus B starts with the call sign first | |
| 00:18 | clumped together and the sign is reversed over here and | |
| 00:23 | then sign is convert clumped together if it's called A | |
| 00:27 | plus B , the sign is changed over here . | |
| 00:30 | The second thing that we need to know is consigned | |
| 00:32 | X is minus half its in quadrant . Second then | |
| 00:36 | we have here sign is going to be a positive | |
| 00:39 | because in second quadrant science positive using the pythagorean theorem | |
| 00:43 | and we can find what the opposite side is and | |
| 00:46 | the sign for this angle is square root of 15/4 | |
| 00:50 | . Now let's read this up together , finish this | |
| 00:52 | problem . Alright , so here's our solution called senpai | |
| 01:06 | over six minus X . Using the expansion formula . | |
| 01:09 | And here's my exes in the second quadrant , given | |
| 01:13 | that call sign is minus 1/4 X components is the | |
| 01:18 | call sign and white components is going to be the | |
| 01:20 | sign . So science is going to be positive in | |
| 01:23 | the squad room for the angle were given plug it | |
| 01:26 | back in there . We have the final over here | |
| 01:28 | . Well , I hope this helps . Hi , | |
| 01:30 | this is dr pan recording from 2000 Arizona . Please | |
| 01:34 | come and share or like this video together . We | |
| 01:36 | can make math easy again , have a confident day | |
| 00:0-1 | . |
