Question
Find $c$ so that one revolution about the $z$ axis of the helix gives an increase of $\Delta z$ in the $z$ -coordinate.$$x=2 \cos t, y=2 \sin t, z=c t, \Delta z=15$$
Step 1
Since x and y are given in terms of sine and cosine functions, one revolution corresponds to a change of 2π in the parameter t. So, we have: Δt = 2π Now, we want to find the increase in the z-coordinate after one revolution. We can use the equation for z: Δz = Show more…
