# Two twin-engine planes like the Cessna 3l0 and derivatives normally function with the engines counter-rotating at least once they are at cruise altitude also do the engines run in synch?

Twin engine aircraft do not have counter-rotating engines. While this would make sense from an aerodynamic engineering point of view, it would greatly increase the complexity of the aircraft, having to design and produce two completely different engines for one aircraft.

The engines do not run in synch per se, but once at cruise speed and altitude, the pilot will make minor adjustments to reduce any excessive wave-harmonic vibrations.

Derivatives are used to find instantaneous rate at which a function changes.

### Where can one find more information about derivatives markets?

A great resource for information on derivatives markets is the International Swaps and Derivatives Association website. The search function in the upper right corner of the front page will take you to downloadable .pdf files on a wide range of subjects under the umbrella of derivatives.

### What is the use of a differential?

Differentials can be used to approximate a nonlinear function as a linear function. They can be used as a "factory" to quickly find partial derivatives. They can be used to test if a function is smooth.

The boiling point depends on altitude (pressure). The effect on the melting point is not significant.

### What is the formula of the divergence of the function?

The divergence of the function is generally a cross product of partial derivatives and the vector field of F. Mathematically, the formula is: div(F) = &part;P/&part;x i + &part;Q/&part;y j + &part;R/&part;z k where: F = Pi + Qj + Rk has the continuous partial derivatives.

### What is the fundamental for finding derivatives of a function?

Not quite sure what you mean with "the fundamental"; I assume you want to know how to do it. You basically need to either memorize or look up the different formulae for finding derivatives - such as the formula for a power (variable in the base), for an exponential function (variable in the exponent), for a sine, for a product, etc. - and apply them to a particular case.

### What are the practical applications of limits of function?
