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

expand

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

- 2 cos (x) + 2

Solution steps

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

Expand

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

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

Rewrite using trig identities

= - 2 cos (x) + 2

(x + \frac{3}{4})^{2}

6 (3 e^{3 x} cos (2 x) - 2 e^{3 x} sin (2 x))

2 - (sin (x) + cos (y)) 2 - (cos (x) + sin (y)) 2

(x + 2 - 3) (x + 2 + 3)
