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}

Doss [256]

Given parameters:

Length of the gift box = 8 inches

Width of the box = 3 inches

Height of the box = 4 inches

Unknown :

Length of its longest diagonal = ?

Solution:

This is a rectangular box.

To find the diagonal of such box, let us use the formula below;

             Diagonal  = \sqrt{l^{2} + w^{2} + h^{2}   }

l is the length

w is the width

h is the height

Input the parameters and solve;

           Diagonal  = \sqrt{8^{2} + 3^{2} + 4^{2}   }   = 9.4inches

The diagonal of the box is 9.4inches
