    Uniform Circular Motion of a Spherical Earth

    Homework Statement In this question, the Earth is modeled as a uniform sphere of radius 6400km. Objects are released from points just above the Earth's surface at the equator and at the North Pole. Which will fall to the Earth with the greater acceleration and by how much? Homework Equations...

    Tangent to Parametric Equations

    Cheers for the link, just had a look at the article. Would this mean that at the cusp, a tangent would not exist or would it simply be a vertical line at x = -pi/2 ?

    Tangent to Parametric Equations

    Homework Statement Consider the curve with parametric equations: x = t - cos t, y = sin t. Determine exactly the equation of the tangent to the curve at the point where t=-0.5pi. Homework EquationsThe Attempt at a Solution The equation of a line is y - y1 = m ( x - x1 ) I substituted t = -pi/2...
