    Multiplying trig functions

    I need to find out "t" in the following

    sin^4 (t) * sec (t) = 1-[x^2/2*r^2]

    How do I multiply this and find the value of t?

    is this your equation (was not sure what r^2 was... radius?)

     <br />
sin^4 (t) sec (t) = 1-\frac{x^2}{2r^2}<br />

    r is a constant (radius) and yes that is the equation.

    not sure how you can find the value of t
    unless x and r are first given values

    x and r do not need to be given, the OP has to use trig identities such as \sec(t) = \frac{1}{\cos(t)} on the LHS to reduce the number of times t appears.

    Then I am left with:

    sin^4 (t) / cos (t) which is where I came from.
