Q1 Show that eqn    x=asinx + b where 0<a<1 ,b>0 has at least one positive root which does not exceed b+a

Q2 Show that polynomial of odd degree has at least one real root

Q3 Evaluate limit and sketch their graph

2)This is simple.Polynomials of odd degree always have atleast one real root bcoz imaginary roots always occur in pairs.So,for a polynomial of degree 2n+1,there can be almost 2n non-real roots and so,there will be atleast 1 real root.

plzzzzz solve using concept of limits.........
