haha wowwww. this ISNT HOMEWORK. Its an random inquiry. It was not assigned, hence I used the word "challenged." jeez. what's the point of this forum if people don't discuss the issue and rather the process of bringing up the issue. some people really just need to take a step back and think...

What I'm saying is I have no idea or clue whatsoever what any of those uses you listed are.

ya its funny. i looked there. there arent any uses listed. just types and calculations.

We are studying RC circuits in my physics class and I'm just curious as to what they are even for? My instructor challenged us to go find 5 uses for RC circuits and I am stumped. I can't even find any on google. Anybody know of any?

Homework Statement Derive an equation that relates the velocity of a freely falling particle to its altitude. Assume that the particle is released from rest at an altitude from the Earth's surface. Express your answer in terms of the variables and , constant gravitational acceleration at...

id love to correct you but I am somewhat stumped as to what you mean.\ I am only aware of using the ftc of calculus to caluclate a line intergral with two points but if it works this way then awesome.

Homework Statement Without parameterizing the path, determine what the value of the line integral (integral of F dot dr) is, if C is the closed, oriented path that travels around the triangle with vertices (0,0) (5,2), and (-3,6) and F=yi + xj Homework Equations Curl possiblY? The...

Homework Statement If s is a unit sphere, centered on the origin and oriented outward, and the flux integral is eual to zero, does F=0? Homework Equations The Attempt at a Solution

Are area vectors of oriented surfaces always perpendicular to the surface?

the curl test is a test to find if a vector field is path independent by taking the partial derivative of F1 and F2 of a function F with respect to x, for F2, and with respect to y, for F1. Basically I am havin trouble finding 3 facts to incur about this F after the curl test.

Homework Statement F=-ysin(x)i+cos(x)j Homework Equations Can the Curl test be applied to this vector field and state three facts you can deduce after applying the curl test. The Attempt at a Solution

i was referring to the df/dy-dg/dx.

trying to remember rules for curl test applicability. is it just simple closed curve? is F=-ysin(x)i+cos(x)j able to use the curl test?
