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?

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 - Jan 7th 2010, 01:09 PMpickslides
x and r do not need to be given, the OP has to use trig identities such as 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.
