simplify (1-sin(x))*(1+sin(x))

simplify

(1 - sin (x)) \cdot (1 + sin (x))

cos^{2} (x)

Solution steps

(1 - sin (x)) (1 + sin (x))

Expand

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

= 1 - sin^{2} (x)

Rewrite using trig identities

= cos^{2} (x)

- x^{3} + 9 x^{2} - 27 x + 27

\frac{7}{3} + \frac{11}{5}

18 a^{2} - 5400 - 360 a

\frac{4}{7} \cdot 2
