To calculate radicals use the square root key. For higher index roots use [SHIFT][X^y]. You need to enter the index before pressing the key. Or use the general power key but with exponent (1/n) where n is the index of the root.
Depending on the actual log function you are talking about, the inverse function (what you call the anti log) can be one of several things. The inverse of the natural log (LN) is the exponential function e^x. If y= ln(x) then x=e^y On a calculator functions that are inverse of one another share the same physical key. If one function is marked on a key, the inverse function is usually the SHIFTED (or 2nd) key The inverse of the common (decimal logarithm) is the power function with 10 as base. Example: if y= log(x) then x=10^y For an arbitrary base (must be positive) if y= log_b(x) then x=b^y. Note: I do not think that the FX-300ms can perform log calculations in bases other than e (natural log) or 10 (common decimal log).
For common antilog, use 10^x, the shifted function of the log key. For natural antilog, use e^x, the shifted function of the ln key. In either case, press the appropriate function and then enter the expression whose antilog you're seeking.
Hi, While the calculator will help you in finding, rather quickly, the answer to a computational problem, it is no substitute for understanding. Had you remembered that the k means kilo or times 1000, you would have calculated the result right away, by hand or with the calculator.
Let us try again 508 g /1.3 kg=508/1300g = 0.39078 about 0.3908 or 39.08 %
Hi, To change the default angle unit, you press the [MODE] button a
certain number of times until display shows a rectangle inside which Deg Rad Grad appear on the top line and 1 2 3 on bottom line, with 1 under Deg, 2 under Rad, and 3 under Grad. Press
the number key corresponding to your case, 1. All angle values you feed
the trigonometric functions will be considered to be in degrees. If you
use the inverse trigonometric functions to find angles, the results
will be in degrees.
Hope it helps. Thank you for using FixYa and do not forget to rate this free solution.
Hello, If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.
hello, Use [SHIFT] [COS^-1], [SHIFT][SIN^-1] and [SHIFT][TAN^-1] the keys are the same as the direct function, but they are accessed via [SHIFT]. Be carefule with the angle units when handling trigonometric and inverse trigonometric functions Hope it helps
