Magnification
As per sign convention for lenses, the height of an inverted and real image is negative and hence the magnification of a lens is negative when it produces an inverted and real imag..
Working of an Eye
The light coming from an object enters the eye through cornea and pupil. The eye lens converges these light rays to form a real, inverted and diminished image on the retin..
Inversion
When a segment of chromosomes breaks but later rejoins after rotating by 180 o it result in inversion. If the centromere is included in the inverted segment, it is known as pericentric but of inversion occurs only in one arm and the centromere is not involved, it is referred as paracent..
Inverse of a Square Matrix
Let A be a square matrix of order n. If there exists a matrix B of order n such that AB = BA = I, where I is the identity matrix of order n, then the matrix A is said to be invertible and B is called the inverse (or reciprocal) of ..

The Human Eye and the Colourful World
The eye lens converges these light rays to form a real, inverted and diminished image on the retina. The light sensitive cells of the retina gets activated with the incidence of light and generate electric signal..
Case III
For both type of lenses, the height of the object is always positive, while the height of the image may be + or - depending upon its nature. As per sign convention for lenses, the height of an inverted and real image is negative and hence the magnification of a lens is negative when it ..

To prove that oxygen is evolved during photosynthesis
Experiment to show release of oxygen during photosynthesis Take a few healthy twigs of Hydrilla, a water plant. Place it in a funnel and invert the funnel in a beaker of water. Invert a test-tube over the stem of the funnel. Leave the set-up in sunlight. After sometime, bubb..

In other words, a square matrix A is invertible if and only if A is a non-singular matrix. (c) If A and B are invertible square matrices, then (AB) - 1 = B - 1 A - 1 (d) If A and B are two non-singular square matrices of the same order, then AB and BA are also non-sin..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
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.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
Looking for More Help!
