I-Calculator ye-Science
A full scientific calculator with trig, logs, powers, roots and constants — free and online.
Malunga nale Calculator
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.
Imibuzo ebuza rhoqo
Ndisebenzisa njani amaqondo endaweni yeradians?
Sebenzisa i-DEG/RAD toggle. Kwinkqubo ye-DEG, sin(90) inika 1; kwinkqubo ye-RAD, sin(π/2) inika 1. Lenkqubo isebenza kuzo zonke iinkonzo ze-trigonometric.
Ingaba ilandela umgca wokusebenza?
Ewe. Ichaza ngokuzenzekelayo ubeko lwephepha lonke kwaye isebenzisa ubeko lwephepha oluqhelekileyo - izibiyeli, emva koko i-exponents, emva koko ukuphindaphinda nokwahlula, emva koko ukongeza nokukhupha.
Ziziphi iinkonzo ezixhaswa?
Le khadi letyala lixhasa i sin, i cos, i tan kunye neentlobo zawo, sinh/ cosh/ tanh, log (isiseko 10), ln, log2, sqrt, cbrt, exp, abs, factorial, kunye nezinto ezingatshintshiyo π, e ne τ.
Ndibala njani i-exponent okanye i-root?
Sebenzisa ^ kwi powers, ngoko 2^10 yi 1024, kwaye sqrt () okanye cbrt () kwi square ne cube roots. I power ephindwe kabini isebenza - 27^ (1/ 3) inika 3 - ngenxa yokuba unikezelo olupheleleyo luchazwe ngeenkcukacha ngempumelelo.
Yintoni utshintsho phakathi kwe log ne ln?
log yisiseko-10 logarithm, ngoko log( 1000) yi 3, ngelixa ln yi logarithm eqhelekileyo kwisiseko e, ngoko ln( e) yi 1. Kukho log2 yesiseko-2 logarithms.
Ndibala njani i factorial?
Ngenisa inani elipheleleyo elilandelelana ngumsebenzi we factorial, umzekelo 5! enika 120 (5 × 4 × 3 × 2 × 1). I factorials ikhula ngokukhawuleza kakhulu, ngoko ke izingeniso ezinkulu zivelisa iziphumo ezinkulu kakhulu.
Ndingasebenzisa i π ne e kwi expression?
Ewe. Uhlobo π (pi) ne e ngqo ngaphakathi kwe expresso, njenge 2*π*5 yokujikeleza okanye e^2, kwaye zitshintshwa ngokuchanekileyo kwabo bonke phambi kokuba expresso ivavanywe.
