Question

Calcule: sen(180-x) - cos (90-x) - tg (360-x)/Tg(180-x)-ccos(360-x)+sen(90-x)

Answer 1

Ola Dessa

E = (sen(180 - x) - cos(90 - x) - tg(360 - x))/(tg(180 - x) - cos(360 - x) + sen(90 - x))

sen(180 - x) = sen(x) 
cos(90 - x) = sen(x) 
tg(360 - x) = tg(-x) = - tg(x) 
tg(180 - x) = -tg(x) 
cos(360 - x) = cos(-x) = cos(x) 
sen(90 - x) = cos(x) 

E = (sen(x) - sen(x) +  tg(x))/(-tg(x) - cos(x) + cos(x) )

E = tg(x)/-tg(x) = -1

.
