    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.

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

    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
