#LIST ALL THE ATTENDANCE QUESTIONS FOLLOWED BY THEIR ANSWERS

#Q1:
#a = 5th RUID
#b = 2nd RUID

#x^a + b*x^(2*a)*y^3

#f_x = 
#f_y = 

#A1:

#a = 0
#b = 9

#x^0 + 9*x^(2*0)*y^3
#1 + 9*1*y^3
#1 + 9y^3

#f_x = 0
#f_y = 27y^2


#Q2:

#x^a  * y^2 * z^b + x^2 * y^(3*b) * z^3


#A2:

#x^0  * y^2 * z^9 + x^2 * y^(3*9) * z^3 = e^xyz
#1 + y^2 z^9 + x^2 * y^27 * z^3 = e^xyz

#Q3:

#Using the equation given, find f_y rather than f_x

#A3:

#2 = 1 + z' + 1 + 4z'
#z' = 0

#Q4:
#is it the same z' = 0?

#2y = x(z + yz') +x(z^z^4 + y^4*z^3 * z')

#A4:

#2 = 1 + z' + 1 + 4z'
#z' = 0
#yes
