Your notation is difficult to read. For magnitudes, which I think is what you're trying to convey here, just use the "pipe" character - |. On my keyboard it is above the backslash key, \.Math9999 said:If \parallel u\=2, \parallel v\=√3, and u*v=1, find \parallel u+v\.
The best way to check if your answer is correct is to review the problem and solution step by step. Make sure you understand the concept and have followed all the necessary steps to arrive at the answer. You can also ask a peer or teacher to double check your work.
If your answer does not match the provided answer, it could be due to a mistake in your calculations or misunderstanding of the problem. Go back and carefully review your work to see if you made any errors. If you are still unsure, seek clarification from a teacher or peer.
There is no specific format for checking your answer, but it is important to make sure you have followed all the necessary steps and have provided a clear and concise answer. You may also want to check if your answer makes sense in the context of the problem.
The best way to improve your accuracy in checking answers is to practice regularly and pay attention to the steps you are taking to arrive at the solution. It is also helpful to seek feedback from teachers or peers to identify any areas of improvement.
Using a calculator to check your answer can be helpful, but it is important to also understand the steps and concepts behind the solution. Calculators can make mistakes, so it is always a good idea to double check your work by hand as well.
