For the following parameterized curve, find the unit tangent vector: r(t)=⟨9cos(t),9sin(t),4cos(t)⟩, for 0≤t≤π. Parametric Curve: If a curve is defined in terms of a new parameter (say ′t′), instead of x and y, th...
Let r(t) = \left \langle \sin 3t, \ln(\sin 3t), \cos 3t \right \rangle for 0 < t < 3. Find the unit tangent, unit normal, and binormal vectors at t = \frac{\pi}{6}. Find the unit tangent vector T, the unit normal vector N, and the unit...
Step 1First,we'll need to get the tangent vector to the vector function.The tangent vector is,1/rr't)=|-7e^(2t)t,-(48)/(t^4),-1|Note that we could use the unit tangent vector here if we wanted to but given how messy those tend tobe we'll just go with this.S...
