OUTPUT:
POLYNOMIAL DIFFERENTIATION
Enter the 1st term in the polynomial with coeff & Power
25 4
do u want to add another node
y
Enter coeff & power
12 3
Interested in adding another node
y
Enter coeff & power
1 1
Interested in adding another node
y
Enter coeff & power
10
0
Interested in adding another node
n
25X^4+12X^3+1X^1+10
Differentiation is
100X^3+36X^2+10
