expand cos^2(x)(sec(x)-1)

expand

cos^{2} (x) (sec (x) - 1)

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

Solution steps

cos^{2} (x) (sec (x) - 1)

Apply the distributive law:

a (b - c) = ab - a c

cos^{2} (x) (sec (x) - 1) = cos^{2} (x) sec (x) - cos^{2} (x) \cdot 1

= cos^{2} (x) sec (x) - cos^{2} (x) \cdot 1

Apply rule:

a \cdot 1 = a

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

= cos^{2} (x) sec (x) - cos^{2} (x)

ln (\frac{( 2 x + 7 )}{y ^{3} + 3})

\frac{4 q ^{2} - 4 q r + b r - q}{4 ( b r - q ) ( q - 1 ) ^{2}}

x^{\frac{1}{2}} (x^{\frac{4}{5}} - x^{\frac{7}{5}})

(1 + \frac{x - 1}{x}) (1 - \frac{1}{x + 1})
