expand sec^2(θ)(1+cos(θ))

expand

sec^{2} (θ) (1 + cos (θ))

sec^{2} (θ) + sec^{2} (θ) cos (θ)

Solution steps

sec^{2} (θ) (1 + cos (θ))

Apply the distributive law:

a (b + c) = ab + a c

sec^{2} (θ) (1 + cos (θ)) = sec^{2} (θ) \cdot 1 + sec^{2} (θ) cos (θ)

= sec^{2} (θ) \cdot 1 + sec^{2} (θ) cos (θ)

Apply rule:

a \cdot 1 = a

sec^{2} (θ) \cdot 1 = sec^{2} (θ)

= sec^{2} (θ) + sec^{2} (θ) cos (θ)

(x - 3) (x^{2} - 4 x + 3 x - 43)

- \frac{20 x}{( x ^{2} - 1 ) ( x + 0.1 )}

(x - 8 + 2)^{2}
