Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Hoe gebruik ek grade in plaas van radiale?
Use the DEG/RAD toggle. In DEG mode, sin(90) gives 1; in RAD mode, sin(π/2) gives 1. The mode applies to all trigonometric functions.
Volg dit die volgorde van operasies?
Ja. Dit ontleed die hele uitdrukking en pas standaard prioriteit toe π hakies, dan eksponent, dan maal en deel, dan optel en aftrek.
Watter funksies word ondersteun?
Hierdie wetenskaplike sakrekenaar ondersteun sonde, cos, tooi en hulle inverses, sinh/cosh/tanh, log (basis 10), ln, log2, shrt, cbrt, exp, abs, anial, en die konstantes π, e en rizon.
Hoe werk ek 'n eksponent of 'n wortel uit?
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.
Wat is die verskil tussen log en ln?
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.
Hoe bereken ek'n faktor?
Gee 'n hele nommer gevolg deur die faktoriële funksie, byvoorbeeld 5! wat gee 120 (5 × 4 × 3 × 2 × 1). Fakulteits groei baie vinnig, so groot invoerpe lewer baie groot resultate.
Kan ek π gebruik en e in'n uitdrukking?
Ja. Tipe π (pi) en e direk binne 'n uitdrukking, soos 2* π*5 vir 'n omtrek of e^2, en hulle word vervang met hul volle presisie voor die uitdrukking beoordeel word.
