simplify (xcos(x)-sin(x))(-cos(x))

simplify

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

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

Solution steps

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

Apply rule:

a (- b) = - ab

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

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

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

lo g_{4} (4) (x - 3)

11 (8 r + 3) - 2 (- 9 = 6 r)

\frac{( x - 1 ) ^{2}}{4 x}

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

(y 6 - 3) (y 6 + 3)
