    Do I understand Stokes' theorem? (Calc 3)

    Here's where I try to explain Stokes' theorem in my own words and you tell me if I'm right / what I need to clarify on. Essentially, it's a method to compute a line integral around a closed curve in three dimensions, with a given vector field F, without having to parametrize this field and...

    Double Integrals for Volume in the First Octant: Iterated Integral Methods

    Homework Statement Set up the following as a double integral whose value is the stated volume, express this double in two ways as an iterated integral, and evaluate one of these. Homework Equations Volume, in the first octant, bounded by - z = 4- (y^2) x=0 y=0 z=0 3x + 4y =12...

    What is the tangential acceleration of a flywheel particle during deceleration?

    Homework Statement The flywheel of a steam engine runs with a constant angular speed of 375 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 1.8 h. At the instant the flywheel is turning at 75 rev/min, what is the tangential component of the linear...

    Equation for a circle in terms of constants A and B

    [Homework Statement If 0<a<b, find the radius R and center (h,k) of the circle that passes through the points (0,a) and (0,b) and is tangent to the x-axis at a point to the right of the origin. Homework Equations ((x-h)^2) + ((y-k)^2)=R^2 (equation of the circle centered around (h,k))...
