expand (5,-4)y(-3,-6)

expand

(5, - 4) y (- 3, - 6)

- 5 y, 3, - 5 y, 6 + 4 \cdot 3 y, 4 \cdot 6

Solution steps

(5, - 4) y (- 3, - 6)

= (5, - 4) (- 3, - 6) y

Expand

(5, - 4) (- 3, - 6) : - 5, 3, - 5, 6 + 4 \cdot 3, 4 \cdot 6

= y (- 5, 3, - 5, 6 + 4 \cdot 3, 4 \cdot 6)

Expand

y (- 5, 3, - 5, 6 + 4 \cdot 3, 4 \cdot 6) : - 5 y, 3, - 5 y, 6 + 4 \cdot 3 y, 4 \cdot 6

= - 5 y, 3, - 5 y, 6 + 4 \cdot 3 y, 4 \cdot 6

(3 sin (x) - cos (x))^{2} + (sin (x) + 3 cos (x^{2}))

(320 i, - 256 j, 128 k) \cdot (\frac{1}{3} i, \frac{2}{3} j, - \frac{2}{3} k)

\frac{1}{x ^{2} + y ^{2}} \cdot (2 \cdot x, - 2 \cdot y)
