# Tangent line to curve Q

Can anybody help me out with this Q?

"A curve R in space has vector equation:

$$x = (sin(\pi u), u^2 - 1, u^2 + 3u + 3)$$

u is a real number. Find a vector equation of the tangent line to R at the point (0, 0, 1)"

What are your ideas or thoughts on how to solve this problem? You need to show some work to get help.

Well, I originally thought of taking the gradient of x and then plugging in the values of (0,0,1). Not sure if this is the right way to go about it though.
