Please help me to conceive and designing an engineering mathmatical which can use laplace transform, the problem closed to our daily live is best.

Expert Solution

1) One uses the Laplace transform to study the transient response of a circuit. Like, when you turn it on, what happens as current flows to charge the capacitors in the circuit to their normal operating voltage. With the proper use of the transform one can see the transient voltage drop in each resistor caused by the charging current.

For the steady state response one uses the Fourier transform, which has many similarities with the Laplace transform.

2) I can't really give you a good example a problem where you need it exactly, but I can maybe try to explain why it's useful. The LaPlace transform takes a differential equation and turns it into a linear equation, so it's easier to solve by algebra, rather than calculus. Then we can take the inverse LaPlace transform and solve for the answer.

3) Laplace transform is integral transform named after its discoverer named Pierre Simon Laplace. It can be used as follows:

It is used in nuclear physics.

It is used in determining structure of astronomical object from spectrum

4) Stability is a concern in any 'real' system. So yes, Laplace transform is used in real life.

Corporate governance is a tough process for me to grasp. Please help me understand this by discussing the relevance of corporate governance. What does it look like? How can a company benefit from governance systems; i.e. what benefits are provided to decision makers? If possible please provide an industry example of corporate governance that you know of or have been involved in from research to further help explain this concept. Thanks!

Use laplace Transform in solving the ff.: After cooking for 45 minutes, when a cake is removed from an oven its temperature is measured at 300°F. 3 minutes later its temperature is 200°F. The oven is pre heated, and so at t=0, the cake mixture is at the room temperature of 70°F. The temperature of the oven increases linearly until t=4 minutes, when the desired temperature of 300°F is attained; thereafter the oven temperature is constant 300°F for t is...
