Engineering Mathematics Every new engineer must learn early that it is never good taste to designate the sum of two quantities in the form:
Anyone who has made a study of advanced mathematics is aware that: 1 = ln e and that 1 = sin2x + cos2x
Therefore, Eq. (1) can be expressed more scientifically as: ln e + (sin2x + cos2x) = This may be further simplified by use of the relations: 1 = cosh y Equation (2) may therefore be rewritten: ln[ At this point it should be obvious that Eq. (3) is much clearer and more easily understood that Eq. (1). Other methods of a similar nature could be used to clarify Eq. (1) but these are easily discovered once the reader grasps the underlying principles. |
