<span>when an object is submerged in the water it losses its weight as accordinglyto</span>
There is an identity of sin(2pi-x) = -sin(x) and cos(2pi-x) = cos(x). This is what we are going to use.
<span>(7pi/6) = (2pi)-(pi/6)
</span>
Therefore:
<span>
1) sec(7pi/6) = 1/cos(2pi-(pi/6)) = 1/cos(pi/6) = 2sqrt(3)/3
</span>
<span>2) cos(7pi/6) = cos(pi/6) = sqrt(3)/2
