simplify e^{-i(wt-pi/4)}

simplify

e^{- i (wt - \frac{π}{4})}

cos (\frac{- 4 wt + π}{4}) + i sin (\frac{- 4 wt + π}{4})

Solution steps

e^{- i (wt - \frac{π}{4})}

Apply imaginary number rule:

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

= cos (\frac{π - 4 wt}{4}) + i sin (\frac{π - 4 wt}{4})

\frac{3 ( 28681 - 53 )}{196}

- 3 (x^{2} - 6 x + 8)^{2}

(1.4) (2 x - 4 y = 0)

10 2^{2} - 9 8^{2}

\frac{x ^{2} ( x - 3 )}{( x + 3 ) ^{2}}
