Maxima and Minima
Maxima and Minima - A function f(x) is said to have a local maximum at x = a, if $ is a neighbourhood I of 'a', such that f(a) f(x) for all x I The number f(a) is called the local maximum of f(x). The point a is called the point of maximum. Note that when 'a' is the point of loc..

It has already been proved that the intensity of a wave is proportional to the square of the amplitude. At a point where constructive interference has occurred, the intensity will be maximum and the amplitudes of the two waves will have added. If A 1 and A 2 are the amplitudes of the individual wav..

Step 2:
Solve f '(x) = 0 to get the critical values for f (x). Let these values be a, b, c. These are the points of maxima or minima. Arrange these values in ascending ord..

Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
