But the HP35s lacks the capability. Following your suggestion, here is a solution of Euler's equation on the HP32S (I like this little machine:): LBL E INPUT X RCL X 0 CMPLXe^X 1 + x^2 x<>y x^2 + RTN Then: FN= E SOLVE X The 32S displays "NO ROOT FND" but the best guess 3.14159265359 is in X. Anyhow, for me it's a complicated way to just solve COS(X)=1. JF
