Solution for Cos(35)=2/x equation:


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

cos(35) = 2/x // - 2/x

cos(35)-(2/x) = 0

cos(35)-2*x^-1 = 0

-2*x^-1 = -cos(35) // : -2

x^-1 = cos(35)/2

-1 < 0

1/(x^1) = cos(35)/2 // * x^1

1 = (cos(35)/2)*x^1 // : cos(35)/2

2*(cos(35))^-1 = x^1

x = 2*(cos(35))^-1

x = 2*(cos(35))^-1
