-sen(1)cos(x) + cos(1)sen(x)=cos(x)
-cos(1)sen(x) = cos(x)-sen(1)cos(x)
Aplicando factor comun:
-cos(1)sen(x) = cos(x)(1-sen(1))
Separando terminos semejantes:
-sen(x)/cos(x) = (1-sen(1))/cos(1)
Aplicando identidad trigonometrica:
-tan(x) = (1-sen(1))/cos(1)
Despejando x
- x = atan((1-sen(1))/cos(1))
x = 0.2854
