Find the curve's unit tangent vector. Also, find the length of the indicated portion of the curve. Choose the correct answer for the unit tangent vector of:1) (sin t)j + (cost)k2) (- cos t)j + (sin t)k 3) (sin 2t)j +(cos 2t)k 4) (-cos 2t)j + (sin 2t)k

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

the answer is 2/54
