El profesor se sorprenderá mucho al ver tu solución correcta😉
exp(sin(1/(9/5)))*cos(1/(9/5))*(-1/(9/5)^2) = x
expsin+1/+9/5))*cos1/+9/5)-1/+9/5^2) = x
-25*cos(5/9)*exp(sin(5/9))/81 = x
x = 0 / ((-x - 25*cos(5/9)*exp(sin(5/9))/81)/x)
sin(5/9) -25*cos(5/9)*e x1 = ---------------------- 81
x1 = -25*exp(sin(5/9))*cos(5/9)/81
suma
sin(5/9) -25*cos(5/9)*e ---------------------- 81
=
sin(5/9) -25*cos(5/9)*e ---------------------- 81
producto
sin(5/9) -25*cos(5/9)*e ---------------------- 81
=
sin(5/9) -25*cos(5/9)*e ---------------------- 81
-25*cos(5/9)*exp(sin(5/9))/81
