Antes de nada, cabe aclarar que:

  • Tg(x) = Tan(x) → Tangente

Calculamos:

 \frac{2 \cos(45°)2 \:  +  \: 3 \csc(37°)}{2 \tan(45°)}

 \frac{2 \:  \times  \frac{ \sqrt{2} }{2}  \:  \times  \: 2 \:  +  \: 3 \csc(37°)}{2 \:  \times  \: 1}

 \frac{ \sqrt{2} \:  \times  \: 2 \:  +  \: 3 \csc(37°) }{2}

  \boxed{\frac{2 \sqrt{2} \:  +  \: 3 \csc(37°) }{2} }

No obstante su valor numérico es aproximadamente:

  \huge\boxed{ \bold{3.90667}}
