(sinx)^8 + (cosx)^8=17/32

I give up.
I have several pages of messy identity calculations, and am not getting anywhere.
so tried some guesses:
x  RS = 17/32 = .53125
.25  .776
.5 .35
.4  .5185
.39  .5359
.395  .5272
.3935  .5298
so there seems to be a solution around x = .3935
I would be interested to know how to do this question.
