Web28 nov. 2024 · Expert Answer The unit normal vector can be found by finding the tangent unit vector of the given equation and then finding the unit vector of its derivative. The given equation is given as: R ( t) = t i + 4 t j, w h e r e t = 2 Taking the derivative of this equation and finding its unit vector will give us the tangent vector. WebThe simplest way to find the unit normal vector n ̂ (t) is to divide each component in the normal vector by its absolute magnitude (size). For example, if a vector v = (2, 4) has a magnitude of 2, then the unit vector has a magnitude of: v = (2/2, 4/2) = (1, 2). Note: Magnitude is another name for “size”.

WebStep 1: Take the derivatives of the components. We have three components, so we’ll need to find three derivatives: This gives us the numerator of the tangent vector formula: r′ (t) = <1, -3sin t, 3 cos t > Step 2 Find the Magnitude of r′ (t) from Step 1.
