Kalkulator Ilmiah
Sebuah kalkulator ilmiah penuh dengan trigonometri, log, kekuatan, akar dan konstan å gratis dan online.
Tentang kalkulator ini
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.
Sering kali mengajukan pertanyaan
Bagaimana cara menggunakan gelar bukan radian?
Gunakan toggle DEG/RAD. Dalam mode DEG, sin Allah Allahn Allah90) memberikan 1; dalam mode RAD, sin Allah Allah harta karun/2) memberikan 1. Mode berlaku untuk semua fungsi trigonometri.
Apakah mengikuti perintah operasi?
Ya, itu menguraikan seluruh ekspresi dan menerapkan standar dasar, dan eksponen, kemudian perkalian dan pembagian, kemudian penambahan dan pengurangan.
Fungsi apa saja yang didukung?
Kalkulator ilmiah ini mendukung dosa, cos, tan dan inverses mereka, sind/cosh/tanh, log (dasar 10), ln, log2, sqrt, cbrt, exp, abs, faktorial, dan konstanta ®, e and ugie.
Bagaimana aku menghitung eksponen atau akar?
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.
Apa perbedaan antara log dan 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.
Bagaimana saya menghitung faktorial?
Masukkan sebuah nomor yang diikuti oleh fungsi faktorial, misalnya 5! yang memberikan 120 (5 × 4 × 3 × 2 × 1). Faktorial tumbuh sangat cepat, sehingga input besar menghasilkan hasil yang sangat besar.
Can I use π and e in an expression?
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.
