Scientific Calculator
Padhai ho ya kaam, kabhi normal calculator kaafi nahi hota. Ye scientific calculator sin, cos, tan, log, ln, root, power aur bracket sab handle karta hai — bilkul free, browser me. Neeche apna expression likhein aur "=" dabayein.
Turant calculator
Formula aasaan bhasha me
Ye calculator aapke likhe expression ko surakshit tareeke se hisaab karta hai. Trigonometry (sin/cos/tan) degree me leta hai — jaisa India ke school-college me aata hai. Bracket, power (^) aur factorial (!) sab support karta hai.
sqrt(16) = 4 · 2^10 = 1024 · log(100) = 2 (base 10)
ln(e) = 1 · sin(30) = 0.5 · 5! = 120 · pi = 3.14159
Order of operation (BODMAS) apne aap sahi lagta hai — pehle bracket, phir power, phir guna-bhaag, phir jod-ghata.
Asli zindagi ke 3 example
Misaal 1 — power aur bracket. 2*(3+4)^2 = 2 × 49 = 98. Bracket pehle, phir square, phir guna.
Misaal 2 — trigonometry. sin(30)+cos(60) = 0.5 + 0.5 = 1. Angle degree me liya jaata hai.
Misaal 3 — root aur log. sqrt(144) + log(1000) = 12 + 3 = 15. sqrt square root, log base-10.
Yahan log phas jaate hain
- Bracket band karna bhoolna. Har khula bracket band hona chahiye, warna error aayega.
- Degree/radian gadbad. Ye tool degree me trig leta hai. sin(30)=0.5. Radian ki aadat wale dhyan dein.
- log aur ln mila dena. log base-10 hai, ln natural (base-e) hai — dono alag natije dete hain.
- Multiply chhodna. 2(3+4) ki jagah 2*(3+4) likhein — star zaroori hai.
- Power ke liye galat chinh. Power ke liye ^ use karein (2^3), na ki **.
Desi context — zaroori baatein
- Students: Physics, maths, chemistry numerical ke liye seedha kaam aata hai — bina app install kiye.
- Degree default: India ke syllabus me angle aksar degree me hote hain, isliye yahan degree default hai.
- Bina internet: Ek baar page khul jaaye to bina internet bhi chalta hai (PWA install karne par).
- Privacy: Sab hisaab aapke browser me — kuch bhi server par nahi jaata.
Aur thoda samajhte hain
Scientific calculator ki sabse badi taakat "order of operations" (BODMAS) ko apne aap sahi lagana hai. Jab aap 2+3*4 likhte hain, to jawab 20 nahi 14 aata hai — kyunki guna pehle hota hai. Isi tarah bracket, power aur function apni sahi jagah lagte hain. Ye chhoti baatein hi normal aur scientific calculator ka bada farak hain. Isliye jab aap lamba expression likhein, to bracket ka dhyan rakhein — ek galat bracket poora jawab badal deta hai.
Students ke liye ek zaroori tip — is calculator me trigonometry degree me leta hai, jo India ke school-college syllabus ke hisaab se hai. Yaani sin(30) ka jawab 0.5 aayega, radian me nahi. Physics aur maths ke numerical me ye default kaam aata hai. Agar kabhi answer ajeeb lage (jaise sin(30) ka 0.5 na aakar kuch aur aaye), to sabse pehle ye check karein ki aap degree wala jawab expect kar rahe hain ya radian wala. Log aur ln ko mix karna bhi ek aam galti hai — log base-10 hai, ln natural (base-e).
Ek aur cheez jo scientific calculator ko normal se alag banati hai wo hai factorial aur power ka istemaal. Factorial (! chinh) ginti-vinyaas (permutation-combination) ke sawaalon me kaam aata hai — jaise 5! = 5×4×3×2×1 = 120. Power (^ chinh) tab zaroori hota hai jab bade number ya vriddhi (growth) ka hisaab karna ho, jaise compound interest ya vigyaan ke sawaal. In dono ko sahi likhna zaroori hai — factorial ke liye number ke baad !, aur power ke liye do number ke beech ^. Practice ke saath ye aadat ban jaati hai aur lambe se lamba expression bhi ek baar me sahi hisaab ho jaata hai, bina step-by-step likhe.
Isi tarah ke aur hisaab ke liye Percentage Calculator aur LCM/HCF bhi kaam ke hain — ek hi jagah se saara kaam nipat jaata hai.
Ye bhi try kar ke dekhein
Chhote sawaal, chhote jawab
Angle degree me hai ya radian?
Degree me. sin(30) ka jawab 0.5 aayega.
Power kaise likhein?
^ chinh se — jaise 2^10 = 1024.
log aur ln me farak?
log base-10 hai, ln natural log (base-e) hai.
Kya offline chalega?
Haan, page khulne ke baad (ya app install karne par) bina internet chalta hai.
Factorial kaise?
! lagaayein — jaise 5! = 120.
