So I have two parametrized equations for two different 3d curves:(adsbygoogle = window.adsbygoogle || []).push({});

Rm(t) = (1.2*sin(2πt) + 0:3)+ ti^{4}+ 1.1cosj^{2}(2π(t + 0:2))k

and

R(t) = Sin(2πt)+ ti^{3}+ Cosj^{2}(2πt)k

I need to figure out if these two curves come within a certain distance of each other (0.5).

I cannot understand how to find the shortest distance between these two curves if I'm not given the specific points where these two curves are closest.

Any help is very appreciated!
