I have stored the quadratic formulas and the vertex formulas for a parabola, -B/2A, (4AC-B^2)/4A. **Q: I bought this calculator but upon opening the package I found that the calculator wasn't coming on. Does anybody know how this can be fixed?** A: Before you return, try resting it by a window to charge the solar cells. I have found that if I don't use it for a while it may not come on until it gets a few minutes "in the sun". I think that it should not do that but after 10-15 minutes it was functioning, and for weeks. **Q: Is this an rpn calculator? similar to hp35s** A: This Calculator (Sharp EL-W516TBSL) does not have RPN abilities. I don't know/ heard of a Sharp calculator having RPN abilities just HP's as of now. I have played and own different types of HP RPN calculators including HP35s, I think RPN is pretty cool and fun to use. I do have an older ver/ model of this Sharp calculator and does not have RPN.
