simplify

(1 + sin (θ)) (1 - sin (θ))

cos^{2} (θ)

Solution steps

(1 + sin (θ)) (1 - sin (θ))

Expand

(1 + sin (θ)) (1 - sin (θ)) : 1 - sin^{2} (θ)

= 1 - sin^{2} (θ)

Rewrite using trig identities

= cos^{2} (θ)

4 m (a^{2} + x - 1) + 3 n (x - 1 + a^{2})

- (x + 4)^{2}

e^{0.99}

2 \cdot \frac{1}{9}

- 5 \cdot (- 7)
