Finally, we may have to make a decision that may be of an industrial nature or
recommend a public policy. For example, the population control model may imply
the policy to stop fishing for 3 years. Or th

Purpose and Structure of the Book
This book provides a comprehensive, thorough, and up-to-date treatment of engineering
mathematics. It is intended to introduce students of engineering, physics, mathematics,
Applying KVL to the collector circuit we get,
VCC ICRC VCE =0-1
VCE = VCC ICRC -2
The above equation is the first degree equation and can be represented by a
straight line. This straight line is DC load line.

In a BJT, indicated the relationship between IB (input) and IC (output). In a JFET, the
of VGS (input) and ID (output) is a little more complicated:

The signal at the output will be 1800 out of phase when compared to the input. The output
is taken across RC with the help of a coupling capacitor. This signal is fed as input to the
next stage i.e. transistor T2. The signal is amplified further and the a

The driving force in engineering mathematics is the rapid growth of technology and the
sciences. New areasoften drawing from several disciplinescome into existence.

Systems of Units. Some Important Conversion Factors
The most important systems of units are shown in the table below. The mks system is also

If VGS = 0 and VDS is further increased to a more positive voltage, then the depletion zone
gets so large that it pinches off the n-channel. This suggests that the current in the nchannel
