Answer:
[tex]\cos^2(u)[/tex]
Step-by-step explanation:
A trigonometry is a branch of mathematics that explain the relationship between the sides and the angles of the triangle.
Hipparchus was the one who makes a table regarding values for a trigonometric function.
It used to measure the distance between landmarks and the distance of nearby stars.
Use [tex]\cot(u)=\frac{\cos(u)}{\sin(u)}[/tex]
[tex]\sin(u)\,\cos(u)\,\cot(u)=\sin(u)\,\cos(u)\,\frac{\cos(u)}{\sin(u)}=\cos^2(u)[/tex]
