Solving an equation on the HP50G (as compared to the Prime)

[rrpalma]

Hello,

Long time HP50G user, but started using the Prime a couple of months ago -- and I find that I quite like it!

Anyways, on page 6-13 of the HP50G User's Guide there is an example of an equation to be solved:

exp(x) - sin((pi*x)/3) = 0

The guide uses the Numerical Solver to solve this equation, and provides 4.5006E-2 as an example solution -- as also found on the HP50G. This however, does not seem to be a correct solution to the equation, for when it is substituted for x on the left side of the equation, we don't get 0.

However, when solved on the Prime, with an initial guess of 1, an initial (correct) solution of {−3.04544793088} is obtained.

Any ideas on how to solve this on the HP50G?

Thanks!!!!
