simplify (1-cos(x))1-1(1+cos(x))

simplify

(1 - cos (x)) 1 - 1 (1 + cos (x))

- 2 cos (x)

Solution steps

(1 - cos (x)) \cdot 1 - 1 \cdot (1 + cos (x))

(1 - cos (x)) \cdot 1 = 1 - cos (x)

1 \cdot (1 + cos (x)) = 1 + cos (x)

= 1 - cos (x) - (1 + cos (x))

Expand

- (1 + cos (x)) : - 1 - cos (x)

= 1 - cos (x) - 1 - cos (x)

Group like terms

= - cos (x) - cos (x) + 1 - 1

Add similar elements:

- cos (x) - cos (x) = - 2 cos (x)

= - 2 cos (x) + 1 - 1

Subtract the numbers:

1 - 1 = 0

= - 2 cos (x)

m (x - y) + 2 n (x - y)

8 (- 6 f - 9) + 2 (9 f + 2)

10 - (y - 6) - y

(x + \frac{1}{2})^{5}

(x - 8) + 8 + 2
