If by "cross" you mean that a pair of curves pass through the same x,y point, then you are trying to determine, for example, if an x value exists in the given range for which
cos(x) = tan(x)
You can use matlab for this purpose if you go about it properly. However playing around with a calculator could accomplish the same thing in this case.
