How do I solve sin(x)cos(x) = 0.458?

[PhysicsAdvice]

How would i solve sinxcosx=0.458, I cannot determine how to isolate the angle, is there a set of identities i could use? Thanks!

There's a double angle identity that involves sin(x)*cos(x). Check your table of identities.

( You DO keep a table of identities handy, don't you? )

Take a look at the trig identities on Wikipedia. You may find something useful.
