expand (3cos(x)+2sin(x))(4cos(x)+6sin(x))

expand

(3 cos (x) + 2 sin (x)) (4 cos (x) + 6 sin (x))

12 cos^{2} (x) + 26 cos (x) sin (x) + 12 sin^{2} (x)

Solution steps

(3 cos (x) + 2 sin (x)) (4 cos (x) + 6 sin (x))

Apply FOIL method

(3 cos (x) + 2 sin (x)) (4 cos (x) + 6 sin (x)) : 12 cos^{2} (x) + 26 cos (x) sin (x) + 12 sin^{2} (x)

= 12 cos^{2} (x) + 26 cos (x) sin (x) + 12 sin^{2} (x)

\frac{( 1 - x - y ) ^{2}}{2}

lo g_{10} (t^{5})

(x + \frac{1}{x})^{8}

6 (5 + 11)

(x + 9 i)^{2}
