RESOLUCIÓN:
[tex] \sec(5x) = \csc(4x) \\ 5x + 4x = 90 \\ 9x = 90 \\ x = \frac{90}{9} \\ x = 10[/tex]
[tex]P = 2 \sqrt{3} sen(6x) + 3tg(4x - 3) - \frac{3}{4} \\ P = 2 \sqrt{3} sen(60) + 3tg(37) - \frac{3}{4} \\ P = 2 \sqrt{3} \times \frac{ \sqrt{3} }{2} + 3 \times \frac{3}{4} - \frac{3}{4} \\ P = 3 + \frac{9}{4} - \frac{3}{4} \\ P = 3 + \frac{6}{4} \\ P = \frac{9}{2} [/tex]
RESPUESTA:
[tex]c) \: \frac{9}{2} [/tex]
