erweitern (sin(θ)+cos(θ))(sin(x)-cos(x))

Lösung

erweitern

(sin (θ) + cos (θ)) (sin (x) - cos (x))

sin (x - θ) + sin (θ) sin (x) - cos (θ) cos (x)

Schritte zur Lösung

(sin (θ) + cos (θ)) (sin (x) - cos (x))

Apply FOIL method

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

= sin (x - θ) + sin (θ) sin (x) - cos (θ) cos (x)

e x p an d (x + 2) sin (x^{2} + 4 x + 17)

e x p an d (1 - 2 cos (x) + cos (2 x))^{2}

e x p an d (tan^{(2)} (y) - cot^{(2)} (y))^{(2)}

e x p an d \frac{2 ( 30 + 7 )}{3}

e x p an d 163 π + \frac{π ( 165 - 8 2 )}{6}
