Write the trigonometric expression in terms of sine and cosine, and then simplify. sin(u) cot(u) cos(u)

Step-by-step explanation:

First, let us simplify cot(u) as follows:

cot (u) =

also,

∴

Hence the original expression becomes:

Next, sin(u) will cancel each other out, leaving the expression below:

hence:

I also found a similar expression with a plus (+) sign after the "sin(u)" online, and if this was your question, the solution will be as follows:

sin(u)+ cot(u) cos(u)

(note that , hence multiplying it with sin(u) does not change anything in the expression.)

Now the relationship sin²(u) + cos²(u) = 1

Therefore:

Hence,
