simplify 3(3sin^2(x)-4cos^2(x))

simplify

3 (3 sin^{2} (x) - 4 cos^{2} (x))

9 sin^{2} (x) - 12 cos^{2} (x)

Solution steps

3 (3 sin^{2} (x) - 4 cos^{2} (x))

Expand

3 (3 sin^{2} (x) - 4 cos^{2} (x)) : 9 sin^{2} (x) - 12 cos^{2} (x)

= 9 sin^{2} (x) - 12 cos^{2} (x)

(- e^{x} + u)^{2}

\frac{d ^{2}}{d x ^{2}} ((y) (x^{4} + y^{4} - 16))

(10 - 6 y) + (x + 3) i

\frac{\partial}{\partial x} ((y) (- 12 x y - 6 y^{5}))

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