1. ## equation

2. if you are just after the number of solutions for $sin(x) = \frac{x}{100}$ rather than the solutions themselves, you can just sketch them and count how many times they intersect.

3. hello : put f(x)=sin(x) and g(x)=x/100
study the intersection of two graphs f,g
remark: -1 <= sin(x) <=1

I think you mean this is the range?

5. I think :-1<= x/100<=1

6. i'm pretty sure for $\frac{x}{100}$ , $x \in \Re$

7. this might give you more of idea....

8. conclusion

it is the ntersection of segement of right and not a right with the graph of function sin (x) xest coach between-100 and 100
100=33pi pi=3.14
-33 pi <= x <= 33 pi
