    Limit Question

    I am trying to find the left hand limit of the following equation

    lim (1/√2)^tan(x)

    as x approaches (pi/2) from the left side.

    I do not know how to solve this problem can I replace tan(x) for t and solve as if the limit was approaching infinity? If anyone could lead me in the right direction I would greatly appreciate it. Thanks

    Think of it logically. As tan(x) approaches (pi/2), what happens?

    the exponent approaches infinity
    now look at this as (1/root(2))^n
    where n approaches infinity

    the value inside the bracket is smaller than one
    so this converges to 0
