    මේක පොඩ් ගැටලුවක්.
    ගැටලුව තමයි ලෝහ මුදුවක් රත් කලාම එහි ආතතිය වැඩි වෙනවද ?
    ලෝහ මුදුවක ආතතියක් නොපවතීද?:rolleyes:
    නැත්නම් ලබා දෙන මුලු තාප ශක්තිය උෂ්ණත්වය වැඩි වීමට පමනක් වැය වේද?

    ඒ ලෙවල් ගාණක් දෙන්න හිතුණා ..ටිකක් අමාරුයි වගෙ

    ගණිත අභ්‍යූහනයෙන් මේක පෙන්නන්න ඕන

    n ඔත්තේ ධන නිඛිලයක් විට

    (1/‍‍‍x ) + (1/y) = [1/(x+y-a ) ] + 1/a නම්

    x^n + y^n = (x+y-a)^n + a^n බව


    ගණිත අභ්‍යූහනය කරලා තියෙන කට්ටිය නිවාඩු පාඩුව ට්‍රයි එකක් දන්න

    malli meka sulu karapuhama (x+y)(a-x)(a-y)=0 kiyala enawa neda..:confused::confused::confused: ethakota me gana nikamma hadanda puluwan wenawaneda? matanam dan abyuhanaya echcharama mathaka na

    ohh ehema enawada ayyee..balamu...thank you :):)

    ko anik awru hari try karala balannako :(...asa hithenawa haduwata passe

    Calculator


    Modern electronic calculators are small (often pocket-sized), digital, and usually inexpensive devices to perform the basic operations of arithmetic.
    In addition, there are scientific calculators and Graphing calculators which focus on operations more complex than those specific to arithmetic.

    Types of calculators


    Basic Calculators -
    Designed to perform basic mathematical operations like +, -, *, /, %, and Square root.

    casiobasiccalculator162.jpg



    Scientific Calculators -
    Designed to calculate problems in science (especially physics), engineering, and mathematics.

    Features of a modern scientific calculator -

    Scientific notation for calculating large numbers
    floating point arithmetic
    logarithmic functions, using both base 10 and base e
    trigonometry functions (some including hyperbolic trigonometry)
    exponents and roots beyond the square root
    quick access to constants such as pi and e

    In addition, high-end scientific calculators will include:

    hexadecimal, binary, and octal calculations, including basic Boolean math
    complex numbers
    fractions
    statistics and probability calculations
    equation solving

    Graphing calculator -

    Calculators that are capable of plotting graphs, solving simultaneous equations, and performing numerous other tasks with variables.
    Most popular graphing calculators are also programmable, allowing the user to create customized programs.

    Features of graphing calculators -

    Graphing
    Calculus
    Complex Numbers
    Economics & Finance
    Linear Algebra
    Probability
    Sequences
    Applications
