    Lightbulb Try iota

    Just try fittin in iota in your calculus equations.
    eg. x^2 = - (ix)^2
    you can then use e^i@ = cos(@) + i sin(@)
    formula to find the answer.
    try it this idea is a serious whirlwind.

    Can you further explain what you are trying to say here?

    Perhaps he's trying to say that the use of complex variables makes many
    problems simpler.

    Yes I Am An Indian

    Yes i am saying it makes problemz simpler, you can also use it if u dont remember a formula etc.

    for example (let | be the integration sign)

    | root of(a^2 - x^2) dx = | root of(x^2 + a^2) dx

    this worx as i is not dependent on x

    but is i a const?

    If this were an identity it would be true when a=0,
    but:

    <br />
\int \sqrt(-x^2)\  dx=\int \sqrt(x^2)\ dx<br />

    so:

    <br />
i\ \int |x| dx = \int |x| dx<br />

    which is false even if we throw in a random \pm sign or two

    Cut and paste from wikipedia:

    "The lowercase Iota symbol is sometimes used to write the imaginary unit but more often latin i or latin j are used."

    Sounds good to me!
