expand 3x^2tan(x)+sec^2(x)(x^3-2)

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

sec^{2} (x) (x^{3} - 2) = sec^{2} (x) x^{3} - sec^{2} (x) \cdot 2

= 3 x^{2} tan (x) + sec^{2} (x) x^{3} - sec^{2} (x) \cdot 2

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

x^{2} y d x - 2 x (x^{2} + y^{2}) d y

\frac{m}{( m x + n ) ( - m x + n )}

\frac{( 2 + y ) ^{2}}{4}

(3 - 3 i)^{7}

\frac{1}{( x ^{2} + 4 ) ( x + 2 )}
