Question: If it is true that tg(2x + 7) = ctg(4x + 35). Calculate the following expression sen(3x+6)+cos(6x-11) E= = sen(4x+5)+cos(6.x +12)

If it is true that tg(2x + 7°) = ctg(4x + 35°). Calculate the following expression


sen(3x+6)+cos(6x-11) E= = sen(4x+5)+cos(6.x +12)

sen(3x+6)+cos(6x-11) E= = sen(4x+5)+cos(6.x +12)
