For f (θ) = √3.cos² (θ) + sen (2θ), a slope of the tangent line, a function at θ = π / 6, is it?

That is an excellent problem. What do you think the slope of the tangent line is? How do you find the slope of a tangent line. On this forum we expect you to solve your own problem with our help. So please post back showing your work.

What is that?

It means sine.

It means "sine" (which I know you know.) I've seen it used only by foreigners (in this case non-US) but I don't know from what country or countries it's used.

I believe "sen" is a standard contraction for "sine" in French.
