expand-x(cos(ln(x))-sin(ln(x)))

expand

- x (cos (ln (x)) - sin (ln (x)))

- x cos (ln (x)) + x sin (ln (x))

Solution steps

- x (cos (ln (x)) - sin (ln (x)))

Apply the distributive law:

a (b - c) = ab - a c

a = - x, b = cos (ln (x)), c = sin (ln (x))

= - x cos (ln (x)) - (- x) sin (ln (x))

Apply minus-plus rules

- (- a) = a

= - x cos (ln (x)) + x sin (ln (x))

(2 x + x^{(2)} e^{(x)})^{(2)}

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

(1.05)^{9}

2 \times 2

(2 x - 3 y - 4 z = 4,) (6 x - 3 y - 8 z = 2)
