I don't ahve time. If you have the equation put in the equation in to maths portal calculator for the equation form you have.  YOu will see there is lots of types of calculators. That will produce a graph in the answer. Just use google other wise to assist you in this respect. Either someon can graph for you over the course of the day if you neeed that assistance or you can problem solve this with the resources available. Good luck.

RE: people don't have a problem with me. Just some troll. Everyone gets them when they are asking questions and trying to learn. No question is too stupid. But the troll, has a sad life and probably cannot construct much in the way of learning. As well, the pity is the troll leaving the comments I believe is a new member. The sad thing is if they were so smart they surely could find questions to answer. See how dumb they are. So I'm not worried they post the comments. I ignore it.

Great answer again Alan. 

Not sure your meaning DragonSlayer554 unless there were troll comments again. 

I really appreciate that you answered the entire question Alan. As you know there is a lot to absorb and mostly its in details such as these. The stuff that is not only hard to hold on to in the memory, but is not common but is important and which also is not covered in depth. This is also compounded by a few general knowledge gaps or logical though processes for understanding the material on the first attempt, for most people. 

Thanks.

Regarding the information of this post: I recall in lectures that for angles less than (a small number of aproximation 13 degrees, the calculator should be in radians, of the top of my head. Was that regarding this wave formula or another area, or in general and can you elaborate please. Thanks.

Um I was doing calculations and my unit notation in meters for waves. Is that not correct? Or where in lies the difference. Thanks agian for a great reply and the time to answer. I have to absorb all that in case it pops up in the exam. Cheers.

You know I'm here to assist the site and its functioning given the posts you guys have to put up with at times. So I think that those who regularly post rather than just answer with numerical answers etc, should/could "title post if there isn't one" in your post, and or use jump to words that the search engine, users and yourself could find. An example is on a post asking how to.. Sqrt(....) and you refer them to surds, you could put "surds and square root" on your post. This also helps to push users to use the large database of information being amassed. Just a thought. But what ever it is you guys choose, it is more work, but with a goal to minimize the work in the future. Ultimately pushing users to title posts accurately/ detailed, is the goal and how nearly every forum would be working online. This shouldn't be an acception, and also it should have stick posts (read before posting) stating guidelines for posts, while those not following said guidlines are removed. I know you're all here to offer free assistance and help, and that all age groups and sorts and country people visit. But it does not have to be extensive. Just a "what is expected" What you can do to make the forum better" or something like it. thanks.

See what you can do with a bit of reading on surds. :) You'd be surprized about how fast you will pick it up. Might be something good on youtube as well. I think Kahn Acadamy would be the first stop. 

I think there is easier way. I'm going to work on this for my own revision. Those logs are what I always forget how to and what to and where to, but don't wait for an answer. Good luck.
