Nezve iyi kalkulator
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.
Zvimwe zvinobvunzwa zvakanyanya
Ndinogona sei kushandisa madhigirii sezviri nyore kupfuura radians?
Usashandisa DEG/RAD toggle. Mu DEG mode, sin(90) inopa 1; mu RAD mode, sin(π/2) inopa 1. Iyo mode inoshandiswa kune zvese trigonometric functions.
Inogona here kutevedzera chirongwa chekushanda?
Yeah. It parses yose pfungwa uye inoshandisa standard kutungamira — parentheses, uyezve exponents, uyezve multiplicity uye division, uyezve kusanganisira uye kubvisa.
Ndezvipi zvirongwa zvinotsigirwa?
Iyo yesainzi kalkulator inoshandisa sin, cos, tan uye zvirevo zvavo, sinh/ cosh/ tanh, log (base 10), ln, log2, sqrt, cbrt, exp, abs, factorial, uye zvizere π, e ne τ.
Ndinogona sei kufungidzira a exponent kana a root?
Usashandisa ^ kune simba, saka 2^10 i 1024, uye sqrt () kana cbrt () kune square uye cube roots. A fractional power zvakare inoshanda — 27^(1/3) inopa 3 — nekuti zvese zvinoratidzwa zvinoparwa nechokwadi chekutevera.
Ndeipi kusiyana pakati pelog ne ln?
log ndiyo base-10 logarithm, saka log (1000) i3, apo ln ndiyo yakanakisisa logarithm yebase e, saka ln (e) i1. Kunewo log2 yebase-2 logarithms.
Ndezvipi zvikonzero zvekuti ndinofanira kuisa pfungwa pazvinhu izvi?
Insert an integer followed by the factorial function, for example 5! which gives 120 (5 × 4 × 3 × 2 × 1). Factorials grow very quickly, so large inputs produce very large results.
Ndinogona here kushandisa π ne e mumifananidzo?
Yes. Type π (pi) and e directly inside an expression, such as 2*π*5 for a circumference or e^2, and they are substituted with their full precision before the expression is evaluated.
