Question

cuanto es -5x(a+c)+2y(a+c)​

Answer 1

Respuesta:

sc(theta) = 1 / sen(theta) = c / a. cos(theta) = b / c. sec(theta) = 1 / cos(theta) = c / b. tan(theta) ... cos(2x) = cos^2(x) - sen^2(x) = 2 cos^2(x) - 1 = 1 - 2 sen^2(x).

Explicación paso a paso:

sc(theta) = 1 / sen(theta) = c / a. cos(theta) = b / c. sec(theta) = 1 / cos(theta) = c / b. tan(theta) ... cos(2x) = cos^2(x) - sen^2(x) = 2 cos^2(x) - 1 = 1 - 2 sen^2(x).
