Simple Maple help

  1. Oct 17, 2005 #1
    Ok, i got two funktions:
    b1:=(x/10)+sin((x/3)+(Pi/2));
    and
    b2:=(1-2*cos((x/4)+(Pi/2)));

    I need to determine all the roots between 0 < x > 30

    If I plot the functions i see that there should be two roots
    plot([b1,b2],x=0..30);

    But when try to get maple to calculate the roots It only comes up with one root:
    fsolve(b1=b2,x=0..30);
    12.83815087

    Thanks and sorry for my bad english.

    Plot the function and get an idea of where the roots are, then tell maple to find the roots in an interval that contains only one of the two roots. So if the roots are 5 and 15, then fsolve([b1,b2],x=0..10) and for the other one 10..30
