x.cos(x) - sin(x) = 0 solve , x ?

Is related to solving tan(x)-x=0:

You should be able to find local zeros using the bracketed root function:

root(x*cos(x)-sin(x),-1,1)=

root(x*cos(x)-sin(x),-5,-4)=

etc.

Success!

The symbolic "solve" will give you just the only exact solution (0).

All the others you'll have to find one by one using one of the numerical methods provided by Mathcad (solve block, root).

Hi liv107,

since it is a transcendent equation, you can solve it only numerically.

More roots - not free
