Thanks...tomorrow I'm going to get my eyes checked.

Not sure what's going one, as soon as I remove the line with String[] arraySuit... all errors go away. With that statement in I get errors on several lines. Cannot figure out what's wrong. /* * Semester Project * Blackjack Class */ package project; import java.util.*; /** *...

r(t) = _ i + _ j, _ <= t <= _ r(t) = (t)i + (t^3)j, 0 <= t <= 6 r'(t) = <1, 3t^2) am I on the right track?

in that case, would I just evaluate the line integral? ∫ f(x(t),y(t))||r'||

Homework Statement Find the work done by the force field F on particle moving along path F(x,y) = -xi + 6yj, <I>C</I>: y = x^3 from (0,0) to (6,216) The Attempt at a Solution Drew the graph in the xy plane (y = x^3 is upper limit, x = 0 is lower limit) W = F ° r'(t) dt Vector field is...

thank you! Not going to make that mistake again. future code posts will have code tags, sorry 'bout that.

Homework Statement Just trying to finish up this assignment, no errors. I run the program, enter a value and a percentage, then click calculate. Program just runs, never displays results. Check my code below, let me know if something is wrong. Driver: package ch7pc1; import javax.swing.*...

ok thanks. Sounds like I wasted a lot of my time, and potentially yours as well as some bandwidth. Thanks again for your time.

I already have the vecor valued function. I'm looking for the points of intersection. How do I find that the surfaces intersect at ((root2), -(root2), 4)?

Homework Statement Sketch the space curve represented by the intersection of the surfaces. Then represent the curve by a vector-valued function using the given parameter. Homework Equations z = x^2 + y^2, x + y = 0, x = t The Attempt at a Solution Space curve sketched (elliptic...
