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}

The length of a rectangle is 3 ft less than twice the width, and the area of the rectangle is 44 ft^2 . Find the dimensions of t
Vinvika [58]

Answer:

Hi there! The width of the rectangle is 5.5ft and the length is 8ft.

Let the width of the rectangle be represented by X. This learns us the length of the rectangle is 2X - 3.

Therefore the area of the rectangle (which is length * width) would be

Since the area of the rectangle is 44 ft^2, we end up with the following equation.

Since X represents the width (and width can't be negative), the width of the rectangle is 5.5ft

The length is

2X - 3 = 2 × 5.5 - 3 = 11 - 3 = 8ft.
