expand (1-e^{jt})*(1+e^{jt})

expand

(1 - e^{j t}) \cdot (1 + e^{j t})

1 - e^{2 j t}

Solution steps

(1 - e^{j t}) (1 + e^{j t})

Apply Difference of Two Squares Formula:

(a - b) (a + b) = a^{2} - b^{2}

a = 1, b = e^{j t}

= 1^{2} - (e^{j t})^{2}

Simplify

1^{2} - (e^{j t})^{2} : 1 - e^{2 j t}

= 1 - e^{2 j t}

(x - 2 y + 5) d x + (2 x - y + 4) d y

(12 - 2 x)^{2} x^{'}

(- 1.3) y (- 10, - 9)

4 e^{(5 + 2 j) t}

t x + (y - x) e^{- k t}
