No I did understand it, I substituted 'cot x = tan(Pi/2 -x)' into my equation, which was my first attempt of many. Thanks anyway for your help, Dylan.

The solution has been found "(Pi/2) - x", just realized that my many hours or stressing was because 'pi' was not written with a capital 'Pi' and syntax would not recognize it. Thanks Dylan.

No this not associated with any integration, the whole question that I was given is what is in the quotation marks. Thanks Dylan.

Hello, I need help trying to simplify the equation below, I believe it should be in terms of x and constants only, no trigonometry. "Simplify arctan(cot(x)), assuming 0<x<pi/2" After many attempted solutions and failures, my most recent attempt is below. let arctan(1/tanx) = u ==> tan...

Thanks for the replys, there seems to be a lot of different opinions and aspects to the Fusion debate. IT will be interesting to see what the future holds with the test reacters.

Hello, I am doing a small research investigation into whether Nuclear Fusion will provide a safer and as efficient energy source as current Fission technology. Just interested if anybody has opinions on the topic and what their stance is on Nuclear Fusion, do they think it can work, any...

Thanks for that, I am currently investigating this and it seems like I have found a possible avenue. Dylan.

Hello, I was just wondering if anybody could give me any ideas about a possible direction in a Physics issues investigation. I am looking at choosing one around nuclear energy and the issues of radiation. Any help or interesting sugestions of avenues in nuclear physics, and or possibe guiding...

Thanks for all the replies.

Thanks for all the replies, I have subsequently looked at wave drag and it has been of help.

Does turbulent flow create more drag due to the exchange of momentum between the slower moving particles and faster moving particles?

Yes I have a book written by John D. Anderson called Fundamentals of Aerodynamics. From what I have studied is right to assume that a shock wave that occurs at a given angle to the flow is an oblique shock wave, and the fluid in the shock increases in density as it is compressed, resuting in...

Its not necessarily homework, however I understand the guide rules, but I agree why it cannot be answered. It is actually a research project which I have to finish as part of my Year 12 which is anoyingly tedious. Anyway I need to have shown evidence that I have asked others for help, and the...

Would anybody be able to give me a simple definition on the question below. Thanks Dylan  What are oblique shock waves? What are expansion waves?

Thanks
