simplify sec(x)-sec(x)sin^2(x)

simplify

sec (x) - sec (x) sin^{2} (x)

cos (x)

Solution steps

sec (x) - sec (x) sin^{2} (x)

Express with sin, cos

= \frac{1 - sin ^{2} ( x )}{cos ( x )}

Rewrite using trig identities

= cos (x)

x^{3} - 8 x^{2} - 9 x + 72

5 (a + 5 b) - 4 a + b

(2 x^{2} y^{3} + 3 x^{4})^{2}

(- 5 x^{2} - 9 x - 5) - (4 x^{2} - 5 x + 3)

\frac{1}{1 + 2 i} + \frac{1}{1 + 6 i}
