expand (cos(2)(x-1))-1

expand

(cos (2) (x - 1)) - 1

x cos (2) - cos (2) - 1

Solution steps

(cos (2) (x - 1)) - 1

Apply rule:

(a) = a

(cos (2) (x - 1)) = cos (2) (x - 1)

= cos (2) (x - 1) - 1

Expand

cos (2) (x - 1) : x cos (2) - cos (2)

= x cos (2) - cos (2) - 1

(1 + tan (x) + sec (x)) (1 + cot (x) - csc (x))

(h) (2 x + 2 h + 6 + 2 x + 3)

(4 - r^{2} + 9 - r^{2})^{2}

\frac{( 0.159 + x ) ( 0.1251 + x )}{( 0.5612 - x )}

\frac{- 3 x ^{2} + 2 x + 3}{2 ( x + 1 ) ( x - 1 )}
