expand 2a^2(1-cos(t))

expand

2 a^{2} (1 - cos (t))

2 a^{2} - 2 a^{2} cos (t)

Solution steps

2 a^{2} (1 - cos (t))

Apply the distributive law:

a (b - c) = ab - a c

2 a^{2} (1 - cos (t)) = 2 a^{2} \cdot 1 - 2 a^{2} cos (t)

= 2 a^{2} \cdot 1 - 2 a^{2} cos (t)

Multiply the numbers:

2 \cdot 1 = 2

= 2 a^{2} - 2 a^{2} cos (t)

11 l e f t (2 a + 3) (3 b - 1) c + 5

\frac{( 2 x - 5 ) ^{2}}{4}

\frac{2 ( 3 x + 8 ) ( 3 x - 8 )}{3 ( x + 2 ) ( x - 2 )}

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