expand (sec(x)-csc(x))(cos(x)+sin(x))

expand

(sec (x) - csc (x)) (cos (x) + sin (x))

- 2 cot (2 x)

Solution steps

(sec (x) - csc (x)) (cos (x) + sin (x))

Apply FOIL method

(sec (x) - csc (x)) (cos (x) + sin (x)) : - 2 cot (2 x)

= - 2 cot (2 x)

(2 + 2 cos (x))^{2}

(\frac{1}{y ^{2}} - \frac{3}{y ^{4}}) (y + 5 y^{3})

(2 x^{2} + x - 3)^{8}

\frac{πk ( b ^{2} + z ^{2} - 2 b z )}{2 a}

(x^{\frac{6}{5}} + 2 x) e^{x}
