Suppose that an object is moving in a space V, so that its position at time t is(adsbygoogle = window.adsbygoogle || []).push({});

given by r=(x,y,z)= (3sin πt, t^2, 1+t)

How to find the direction of the vector along which the cat is moving

at t = 1?

I have no idea where to find out the direction of the vector along which the object is moving.
