O tem kalkulatorju
A scientific calculator handles everything a basic calculator does plus trigonometry (sin, cos, tan and their inverses), logarithms, exponents, roots, factorials and the constants π and e. Type a full expression like sin(45)^2 + log(1000) and it respects the correct order of operations. Switch between degrees and radians for trig.
Rather than pressing one operation at a time, you build up a whole expression and it is parsed as a unit: parentheses are resolved first, then exponents and roots, then multiplication and division, and finally addition and subtraction, exactly as the usual PEMDAS/BODMAS rules require. A DEG/RAD toggle controls whether angles are read in degrees or radians, so sin(90) gives 1 in degree mode while sin(π/2) gives 1 in radian mode. Constants π, e and τ, factorials, absolute value and both base-10 and natural logarithms are all available.
For a worked example, entering sin(45)^2 + cos(45)^2 in degree mode returns 1 (the Pythagorean identity), and 5! + sqrt(144) evaluates to 120 + 12 = 132 because the factorial and square root are taken before the addition. Students reach for it in trigonometry, physics and chemistry homework; it also covers everyday needs like powers, percentages and roots without hunting for a physical calculator.
Pogosta vprašanja
Kako naj uporabim diplome namesto radianov?
Uporabite preklopnik DEG/RAD. V načinu DEG sin( 90) daje 1; v načinu RAD greh( π/2) daje 1. Način velja za vse trigonometrične funkcije.
Ali sledi vrstnemu redu?
Da. To analizira celoten izraz in uporablja standardno prednost – oklepaji, nato eksponenci, nato množitev in razdelitev, nato dodajanje in odštevanje.
Katere funkcije so podprte?
Ta znanstveni kalkulator podpira greh, ker, tan in njihove inverzne, sih/cosh/tanh, log (osnova 10),In, log2, sqrt, cbrt, exp, abs, faktorial, in konstante π, e in λ.
Kako izračunam izkazalca ali korenina?
Use ^ for powers, so 2^10 is 1024, and sqrt() or cbrt() for square and cube roots. A fractional power also works — 27^(1/3) gives 3 — because the whole expression is parsed with correct precedence.
Kakšna je razlika med logom in In?
log is the base-10 logarithm, so log(1000) is 3, while ln is the natural logarithm to base e, so ln(e) is 1. There is also log2 for base-2 logarithms.
Kako izračunam faktorial?
Vnesite celo število, ki mu sledi faktorialna funkcija, na primer 5!, ki daje 120 (5 × 4 × 3 × 2 × 1). Faktorial raste zelo hitro, tako da veliki vhodni materiali ustvarjajo zelo velike rezultate.
Lahko uporabim π in e v izrazu?
Da. Tip π (pi) in e neposredno znotraj izraza, kot je 2*π*5 za območje ali e^2, in so nadomeščeni s svojo popolno natančnostjo, preden se izraz oceni.
