expand cos(θ)(-3,-5)

expand

cos (θ) (- 3, - 5)

- 3 cos (θ), - 5 cos (θ)

Solution steps

cos (θ) (- 3, - 5)

= (- 3, - 5) cos (θ)

Apply the distributive law:

a (b - c) = ab - a c

a = cos (θ), b = - 3,, c = 5

= cos (θ) (- 3,) - cos (θ) \cdot 5

Apply minus-plus rules

+ (- a) = - a

= - 3 cos (θ), - 5 cos (θ)

5 (5 x + 7 x = - 2)

(e^{- x} - 1) (e^{x})

A (1, - 5) y B (- 2, 4)

(- x + 3 y, x + 2 y) y (7, 8)

- \frac{a ( - a ^{2} - 1 )}{b}
