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

  • Maths,Science -

    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.
