simplify 2xy(2pit^3cos(2pist^3))

simplify

2 x y (2 π t^{3} cos (2 π s t^{3}))

4 π x y t^{3} cos (2 π t^{3} s)

Solution steps

2 x y (2 π t^{3} cos (2 π s t^{3}))

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

2 \cdot 2 = 2^{1 + 1}

= x y \cdot 2^{1 + 1} π t^{3} cos (2 π s t^{3})

Add the numbers:

1 + 1 = 2

= x y \cdot 2^{2} π t^{3} cos (2 π s t^{3})

2^{2} = 4

= 4 π x y t^{3} cos (2 π t^{3} s)

(\frac{1 - 2 ( 38.4 )}{38.4})^{4}

(2.14 (10)^{- 2}) (4.28 (10)^{- 2})^{2}

e^{- 2 x} e^{- y}

e^{- 2 x^{2}}

e^{- 2 t} (e^{- t + 1} H (t - 1))^{'}
