expand (3cos(x)-2)(tan^2(x)-1)

expand

(3 cos (x) - 2) (tan^{2} (x) - 1)

3 tan^{2} (x) cos (x) - 3 cos (x) - 2 tan^{2} (x) + 2

Solution steps

(3 cos (x) - 2) (tan^{2} (x) - 1)

Apply FOIL method

(3 cos (x) - 2) (tan^{2} (x) - 1) : 3 tan^{2} (x) cos (x) - 3 cos (x) - 2 tan^{2} (x) + 2

= 3 tan^{2} (x) cos (x) - 3 cos (x) - 2 tan^{2} (x) + 2

\frac{- 3 x ^{2} + 3}{( x ^{2} + 1 ) ^{2}}

(- \frac{1}{2} x + \frac{11}{2})^{2} - (3)^{2}

\frac{\partial}{\partial y} (x^{2}) + y^{2} (1 + x)^{3}

\frac{2 x + 3}{( x - 1 ) ( x ^{2} + 2 x + 2 )}

(- 2 + 3 i)^{10}
