    Evaluating Double Integrals: Switching the Order of Integration

    Ok, thanks! so if I'm not mistaken then, the new equation is: \int^{1}_{0} \int ^{y}_{0} cos(x/y)dxdy ?

    Gradients and Directional Derivatives

    Homework Statement (a) Find two linear equations in the variables x,y,z such that their solution set is the tangent line to the graph of f(x,y) = x^{2} - y^{2} at (2,1,3) which is parallel to the x,z plane. (b) Represent the line of (a) by parametric equations. Homework Equations...

    Parametric Representation of a Plane

    ok, i understand how you can use those 3 points to define the plane since they arent in the same line, and i think i understand why s and t can be any value. Regardless of what value they have, they are are just a coefficient on the (position vector?) kind of like how with the equation y = x...

    Parametric Representation of a Plane

    Homework Statement Give a parametric representation of the plane x + y + z = 5. Homework Equations I am really not sure, I've been over the chapters we've covered for a little over an hour now, and the only mention i can find of a parametric representation of a plane is in passing...

    Solving a Two-Box Frictionless Physics Problem

    I have a big physics test tomorrow:cry: , and I can't figure out how to solve this type of problem: 2 boxes, one on a table attached to a string attached to another box hanging off the table. (the table is a frictionless plane)--It wants me to find the force of tension on the string. the...

    Integration: Partial Fractions

    How does this work? All i really understood from class was that you would factor the integrand and then somehow A and B were involved, and you would use systems of equations to find A and B. What's the middle ground? Thanks in advance!:biggrin:
