expand (sin(x)-1)(cos(x)+1)

expand

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

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

Solution steps

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

Apply FOIL method

(sin (x) - 1) (cos (x) + 1) : cos (x) sin (x) + sin (x) - cos (x) - 1

= cos (x) sin (x) + sin (x) - cos (x) - 1

\frac{( 1 - 3 ) ^{4}}{16} + 3 - 1

(y^{\frac{3}{4}} - 2 x^{\frac{3}{4}})^{3}

\frac{3}{13} \cdot (7 - 3) + \frac{4}{13} (0.25 \cdot 3) + \frac{14}{13} (- 3)

\frac{1 - 3 i}{1 + 3 i}

\frac{1}{x + 4}
