Find the number of solution of the equation `sinx=x^(2)+x+1`.

Text Solution

Verified by Experts

The correct Answer is:
No solution

Let `f(x)= sin x` and `g(x)=x^(2) +x+1=(x+1/2)^(2)+3/4`, which could be graphicaly represented as follows :

As these two graphs do not intersect at any point, the given equation has no solution.
