expand (1+cos(x))^2+(-sin(x))

expand

(1 + cos (x))^{2} + (- sin (x))

1 + 2 cos (x) + cos^{2} (x) - sin (x)

Solution steps

(1 + cos (x))^{2} + (- sin (x))

Apply rule:

a + (- b) = a - b

(1 + cos (x))^{2} + (- sin (x)) = (1 + cos (x))^{2} - sin (x)

= (1 + cos (x))^{2} - sin (x)

Expand

(1 + cos (x))^{2} : 1 + 2 cos (x) + cos^{2} (x)

= 1 + 2 cos (x) + cos^{2} (x) - sin (x)

[\frac{8}{x - 16} + 2 (100 - x)] (x - 16)

\frac{2}{n} (1 + \frac{2 i}{n})^{3}

(- 6, - 3) y (4, 2)

(6 + 2) 4

\frac{11 s}{2 \cdot ( 125 + s )}
