    Solve Limit as x→π/8: (cos(2x)-√(2))/(x-π/8)

    I am not exactly sure about that.

    Solve Limit as x→π/8: (cos(2x)-√(2))/(x-π/8)

    You end up with -(1/sqrt2)/0 limit. the equation is an identity that is supposed to help when solving the question. I also tried expanding the relevant equation and ended up with, cos(2x)+cos(2a)=-2sin(x+a)sin(x-a)
