Well I did it like this
By equation of the sphere its already given that the sphere is at origin (0,0,0).
Now from there we get radius of the sphere is
When I solve the equationas my answer is
And when I solve the equationas my answer is or .
Now which one is correct ,are both correct?
Now putting the different values for "n" we can get the value for theta and put it in the equation and check,but I did just a couple and I know if I can graph it it will show but which application to use for this kind of job I dont know.
Yes stefy I agree with you, but still we use approx symbol for that... don't we ?,in the book they directly used equal symbol.
Bob the topic was about... calculating vectors...
Their are two force vectors given,first one 70N north and another is 50N south west,so calculate the resulting force and direction.
I tried but I can't solve it...
If a,b are two different values of x lying between 0 and 2 pi (i.e.. 0 to 360 degrees) which satisfy the equation 6 cos x + 8 sin x = 9 ,find the value of sin(a + b).
Well what I did was I turned that equation into an quadratic equation and find the roots and also use the relation of the sum of the roots.But no luck my solution is getting no where....
here is what I got when I turned it into an quadratic...
I will purchase a laptop (Dell Inspiron 14R) with it installed.The over all cost seems ok.
Nvidia GeForce GT 730 M is designed for laptops/notebooks,for desktop their are other series both from AMD and Nvidia like Nvidia GTX series is best on desktop platform ,for future I am planning to buy a graphic card from GTX series for my desktop.
Well after more search I found Nvidia 730M doesn't support four non gaming DirectX 11.1 features ,two of them are for 2D which I don't need in my 3D programming and other two seems to be not very useful for my 3D work.The plus point of nvidia is I get features like Optimus, PhysX, CUDA, 3D Vision, FXAA, TXAA, OpenCL, Direct Compute,and much more which could be explored in 3D programming...
So I am going for Nvidia ,I am not concluding AMD is bad but at this very moment the over all advantages is given by Nvidia
Thanks bobbym and Agnishom
Thanks for the reply.
I think NVIDIA GeForce GT 730M score 2 points as its a bit better than AMD Radoen HD 8730M in performance and also it have drivers for linux which are better than ADM's drivers.
But I see AMD Radoen HD 8730M support full DirectX 11.1 in case of NVIDIA GeForce GT 730M it only support some features of DirectX 11.1,that's what making me thinking ,as for 3D development its better to have full DirectX 11.1,but again NVIDIA GeForce GT 730M have PhysX which is an another area I would like to explorer...
Any suggestions ....
I am going to buy a laptop ,is Dell Inspiron any good ...
Two models are quite good for my needs Dell Inspiron 14R and Dell Inspiron 15R
what you guys think about it?
The two models differ in screen size and graphic cards ,the screen size doesn't matters much for me but the graphic card does,so I have two choices
1) NVIDIA GeForce GT730M 2GB VRAM
2) AMD Radoen HD 8730M 2GB VRAM
Both cards are almost similar,so I am confused what should I do...
Well let me tell this first,I am not asking for any solution as I have them ,my problem is something different...
I can do trigonometric prove but only to a limit for example these kind of questions I have no problem
or more general types I have no problems ,but there are some I am having problems and I understand that, I am not understanding the process or steps involved in solving them for example
I am not able to solve these kind problems ,what I need to know is what steps you guys take to solve these kind of problems,actually I feel them very complex.
In short I do not need the solution for question 1 and 2 I need to know how you guys solve these.
Another thing ,my book have very few of these questions so I can't even practice more if you guys have any resource it would be great.
I think the form factor is not 1,as its the case of a square wave,but in the image posted by the OP its not clear what is the time period of the pulse so we can't regard it as a square wave.
For a pulse wave form factor is
Well the image is not good enough to show any kind of electrical transient.But I guess its a pulse..
Any current which is not constant as in case of DC ,is reffer to as AC,even a pulse. In your image it looks like a DC transient.As AC is not constant they are measured differently than DC.In any circuit AC could be measured with Average,Peak-to-Peak,or RMS value.
Now the form factor is the ratio of RMS and Average value.
In your case I cant calculate as it needs more information about the wave,it needs the time period of the pulse.
