expand 3cos(x)(4-tan(x))

expand

3 cos (x) (4 - tan (x))

12 cos (x) - 3 sin (x)

Solution steps

3 cos (x) (4 - tan (x))

Apply the distributive law:

a (b - c) = ab - a c

3 cos (x) (4 - tan (x)) = 3 cos (x) \cdot 4 - 3 cos (x) tan (x)

= 3 cos (x) \cdot 4 - 3 cos (x) tan (x)

Simplify

3 cos (x) \cdot 4 - 3 cos (x) tan (x) : 12 cos (x) - 3 sin (x)

= 12 cos (x) - 3 sin (x)

(i w + 0.5) \cdot (i w + 1) \cdot (i w + 2)

(z + 1 + i)^{2}

\frac{( 8 x - 5 )}{( 4 x - 7 ) ^{2}}

- \frac{16 x ( - x ^{2} + 12 )}{( x ^{2} + 4 ) ^{3}}

\frac{( e ^{3 s} - e ^{4 s} )}{( s - 4 ) ( s + 1 )}
