expand (sin(2θ)+cos(2θ))(sin(θ)+cos(θ))

expand

(sin (2 θ) + cos (2 θ)) (sin (θ) + cos (θ))

sin (2 θ + θ) + cos (2 θ - θ)

Solution steps

(sin (2 θ) + cos (2 θ)) (sin (θ) + cos (θ))

Apply FOIL method

(sin (2 θ) + cos (2 θ)) (sin (θ) + cos (θ)) : sin (2 θ + θ) + cos (2 θ - θ)

= sin (2 θ + θ) + cos (2 θ - θ)

\frac{34 ( s + 4 )}{( s ^{2} + 2 s + 2 ) ( s ^{2} + 16 s + 68 )}

(sin (x + y) - cos (x) sin (y)) \cdot sec (y)

(2 x - \frac{5}{x ^{2}})^{12}

\frac{\partial}{\partial x} ((z) (x + y) e^{y})

(1 + 5)^{4}
