vovangra [49]

Answer:

y = 6x² -13x -5

Step-by-step explanation:

(1,-12) (2,-7) (5,80)

y = ax² + bx + c

-12 = a*1² + b*1 + c = a+b+c (1)

-7 = 4a + 2b + c (2)

80 = 25a + 5b + c (3)

(2)-(1): 3a + b = 5 (4)

(3)-(2): 21a + 3b = 87 (5)

(4)*3: 9a + 3b = 15 (6)

(5)-(6): 12a = 72 a = 6

(4) b = -13

(2) c = -5

How did he get this 1/2i ? I dont remember studying this definition in calc 1 neither calc 2!

Hitman42 [59]

The $i$ in the denominator is missing in the second expression. It should be

$\sin at=\dfrac{e^{iat}-e^{-iat}}{2i}$

This follows from

$e^{iat}=\cos at+i\sin at$
$e^{-iat}=\cos at-i\sin at$
$\implies e^{iat}-e^{-iat}=2i\sin at$
$\implies \sin at=\dfrac{e^{iat}-e^{-iat}}{2i}$
