1. ### 3 Proofs for .9999 = 1

My understanding of infinte numbers is that you can not treat them like any other number. Like what 'tenyear" was talking about. Infinite numbers are just a mathimatical idea and dont realy exist in the real universe as we know it. I thought that is why "limits" were created anyway.
2. ### Find tension in three ropes suspending same mass

A bird feeder is hanging off of a branch by 3 ropes. Rope1 and Rope2 are tied to the branch and both conect to rope3. Rope3 is conected to the birdfeeder. Rope 1 is 60 degrees of the branch and rope2 is 30 degrees. Symbolicly find the tensions of all of the ropes. We know that the tension...
3. ### The Trace Theorem?

The college i go to has weekely "Math talks" where different math proffesers(forgive my spelling) take turns talking about different math subjects. And this weeks lecture was labled "The Trace Theorem and the Hadamard Determinant Theorem". Usually all of the math seminars go over my head, since...
4. ### The Trace Theorem?

I am only in Calc I, and i am going to go to a math seminar on Trace theorem tommorow. And i was curious in simple terms, what it is and what it is used for. Thanks, Steven
5. ### Newton's laws of motion help

Thankyou very much, HallsofIvy. that helped alot.
6. ### Newton's laws of motion help

The problem was pretty simple i thought, but according to the book i get the wrong answer. I think i might be approching the problem wrong. "In the drawing, the weight of the block on the table(block1) is 422N and that of the hanging block(block2) is 185N. Ignoring all frictional effects and...
7. ### Simple Kinematic Question

i might be able to help Im pretty new to physics myself. But I think i will be able to help you, but I am not sure if i am right. First i think we have to find the x component of the intial velocity. We find this by noticing the shuttle angle of attack is 40. So with the laws of trig we use...
8. ### Education question

I am a freshman in college right now. I am going to pursue a physics major. Possibly major in astronomy and physics. I was curious if it would be possible to get a masters in aerospace engineering if I had a gotten a major in physics. Any help in this topic would be greatly appriciated. Thanks...
