Cot(theta -pi/2) = cos(theta - pi/2)/sin(theta - pi/2)
using cosine and sin law
= [cos(theta)*cos(pi/2)+sin(theta)*sin(pi/2)] / [sin(theta)*cos(pi/2) - cos(theta) * sin(pi/2)]
by simplify it :
= sin(theta) / -cos(theta)
= -tan(theta)

The test is worth 80 points.
Each homework assignment is work 25% of the test.
Question asked:
How many points may be earned during this unit ?
Solution:
By unitary method:
Points may be earned from 1 assignments = (given)
=
Points may be earned from 5 assignments =
Points may be earned from 1 test =
Total points may be earned = 100 + 80 = 180
Therefore, 180 points may be earned during this unit.
