expand e^{i(x+ct)}

expand

e^{i (x + c t)}

cos (x + c t) + i sin (x + c t)

Solution steps

e^{i (x + c t)}

Apply imaginary number rule:

e^{ia} = cos (a) + i sin (a)

= cos (c t + x) + i sin (c t + x)

\frac{f ( ( - 3 x - 8 ) + h ) + 3 x - 8}{h}

(- 5)^{3} \cdot (- 5)^{3}

d er v a t e (\frac{50}{x} - 2) x^{2}

(x y - y) (x d y + d y d x)

((x + 1) (x - 1)) \cdot ((x + 2) (x - 2))
