Simplify exactly. Be sure that each part of your final answer is in lowest terms with a rational denominator.

59sec2(30)+38cos2(45)+14tan2(45)=\displaystyle -\frac{{5}}{{9}}{{\sec}^{{2}}{\left({30}^{\circ}\right)}}+\frac{{3}}{{8}}{{\cos}^{{2}}{\left({45}^{\circ}\right)}}+\frac{{1}}{{4}}{{\tan}^{{2}}{\left({45}^{\circ}\right)}}=
