Simplify:
`(1)/(2)[(sqrt(3)/2)cos23° -(1/2)sin 23°]`

(1)/(4)[sqrt(3)cos23^(@)-sin23^(@)]=

(1)/(4)(sqrt(3)cos23^(@)-sin23^(@)) is equal to

Simplify : (1)/(sqrt(3)+sqrt(2))-(1)/(sqrt(3)-sqrt(2))+(2)/(sqrt(2)+1)

1/3 (sqrt3 cos 23^(@) - sin 23^(@))=

Simplify: ((1)/(3)+(3)/(4)((2)/(5)-(1)/(3)))/(1(2)/(3)backslash of (3)/(4)-(1)/(4)backslash of(4)/(5))(1)/(63)(b)(23)/(40)(c)(23)/(55) (d) (23)/(63)

Simplify tan[(1)/(2)cos^(-1)((3)/(sqrt(11)))]

Simplify (1/2+1/sqrt2-sqrt3)/(sqrt3-1/sqrt2-1/sqrt3)

sin^(-1)(-(sqrt(3))/(2))+cos^(-1)((sqrt(3))/(2))
