Customer Review(s)
Customer Rating: Summary: Perfect Intersection of Power, Ease, Price Comment: I've used my hp 33s relentlessly in school for over 3 years for surveying comps, physics, and geodesy. It's now on its third set of batteries. I have several other calculators: hp and ti, graphers, and scientifics, but this is the one I always have with me. The STO(re) button, the x^2, square root, power, x root, e^x, and LN functions are all located together and are available without having to press a shift button. That alone makes this calculator much faster to use. The built-in R>P and P>R functions and the two-line display allow you to work with both the x and y components of vectors simultaneously-another time saver. Yes, you enter an angle and then a distance, hit the >y,x button and you get y and x at the same time. You can sum components in the stat registers or on the stack with the CMPLX function. You can use the equation list with the SOLVE button to solve for any variable in an equation without having to isolate it beforehand. Store your own constants in the equation list explicitly or by having an expression to evaluate it automatically. For example, A constant like this can be stored: 1÷298.257222101. You can find an equation of a line between two points with the linear regression function, get the correlation coefficient between two sets of values. Permutations, combinations, integer math, unit conversions are all available directly on the keyboard. Enter fractions by simply double-tapping the decimal point after entering the numerator, and, you can control the maximum value of the denominator with the /c button. A simple program clears all the memory I need cleared between problems without having to do it manually. The same routine loads whatever physical constants I'm using then (physics). The topmost program on the program list will execute with only a press of the R/S button and this can be exploited to quickly and repeatedly execute a program or repeat an action, such as entering a long column of values needing a conversion before loading into the stat registers or easily computing x(t) and y(t) to get a sequence of the coordinates of a parametric function (particle or projectile motion).
The calculator comes with a real user manual containing several example programs that include coordinate transformations, curve fitting, solution of a system of 3 equations. Online, HP also has a library of short instructional aids (each a few pages long) that concentrate on individual problems and applications. There are also many third-party programs available.
Get one long before you need it for a test. It's much lighter than a grapher and can be used for a majority of calculating needs. Don't be swayed by those comparing the 33s to older HP scientifics. You can't buy them off the shelf now, so it's an illogical comparison. Its only comparison is the hp 35s, which is more powerful and favored by long-time HP users, but the 33s is definitely more accessible and usable out of the box. When you use it in RPN mode, this calculator eliminates a lot of computational drudgery.
