Hello, I want to draw the detailed logic level diagram for a basic computer. For this i found a software that will work which is microsoft visio 2010. But i m not satisfied with that because it has some limitations. Such as re-arranging the wires automatically and also the simulation...

Homework Statement In this circuit i m given that Vs=12cos10t V Calculate the energy stored at t=15ms Homework Equations The Attempt at a Solution i have got I1 and I2 but i m confused how i can get the energy by using dot convention. Should i use -Mi1i2 or +Mi1i2 while...

Thanks a lot :biggrin:

Homework Statement triangle in the plane z=1/2y with vertices (2,0,0) (0,2,1) (0,0,0) please help me to find out the projection of the triangle in xy plane. thanks Homework Equations The Attempt at a Solution

How can i get the image of a integral. Say i have a integral function like this \int_{\pi/2}^{\pi} \int_{0}^{2} r\sqrt{4-r^2} drd\theta Now i want to see what volume the integral giving me. Which software i have to use for this purpose. Thanks

Thanks i have got the solution by your method. But i m confused how the book solved the problem. They have formed an integral like this \int_0^{2\Pi} \int_0^2 \int_{-{\sqrt{20-r^2}}}^{r^2} rdz dr d\theta + \int_0^{2\Pi} \int_0^{\sqrt{20}} \int_{-{\sqrt{20-r^2}}}^{\sqrt{20-r^2}} rdz dr d\theta...

oh sorry yes i was wrong it should be r=+-2. I m confused about the sketch r^2+z^2=20 is a ellipsoid and z=r^2 is a elliptic paraboloid and i m asked to get the solid that is below the elliptic paraboloid ? If it is how can i get the limits of my integration ?

This is the exact question i have copied from the book. The solution of the equation gives me r=+-5^1/2 could you please tell me how to proceed with these types of problems. thanks

Homework Statement The solid that is inside the surface r^2+z^2=20 and below the surface z=r^2 Homework Equations The Attempt at a Solution I m confused how to solve this problem of get a projection and their intersection. Their intersection gives me a equation of...

thank you :smile:

can you tell me how to solve it or refer me to any topics from which i can learn how to deal with these type of problems. Thanks

i m using y=1 as a lower limit of my y limit. Well i want to know if my double integral setup is correct or not and solution too please.

i know and i guess my integration limits are right :smile:

i have uploaded the picture of the region the shaded region i m talking about. http://i30.tinypic.com/2920l6a.png

The term e^{x/y^2} was given in the question i was asked to integrate between the region limits.Then could you please tell me how to get the solution of \int_1^2 y^2e^{1/y^2}\textrm{d}\,y Thanks for the latex info i m still learning. The region is actually in the first quadrant...
