The arc length of a parametric curve over the interval a≤t≤b is given by the integral of the square root of the sum of the squared derivatives, over the interval [a,b]. So to find arc length of the parametric curve, we’ll start by finding the derivatives dx/dt and dy/dt.
Read MoreTo find the arc length of the vector function, we’ll need to use a specific arc length formula for L that integrates the root of the sum of the squared derivatives. L will be the arc length of the vector function, [a,b] is the interval that defines the arc, and dx/dt, dy/dt, and dz/dt are the derivatives of the parametric equations of x, y, and z respectively.
Read MoreThe arc length of a polar curve is simply the length of a section of a polar parametric curve between two points a and b. We use a specific formula in terms of L, the arc length, r, the equation of the polar curve, (dr/dtheta), the derivative of the polar curve, and a and b, the endpoints of the section.
