Angle of elevation
Let O = Position of the observer P = Position of the object OH = Horizontal line through O (line of reference)..
Let O = Position of the observer P = Position of the object OH = Horizontal line through O (line of reference)..Interior and Exterior Angles of Triangle
In a triangle when we refer to an angle, we mean the angle bounded by the two sides. The three angles lie in the interior region of the triangle. These angles are called the interior angles of the triangl..
Angle in standard position
If an angle of any measure be given, one can always construct (or draw) a cartesian co-ordinate reference frame in such a way that the origin is at the vertex of the angle, and positive half of the x axis coincides with the initial side of the angle. When th..

Total Internal Reflection - Let us consider a ray of light passing from glass to air, that is from a denser medium to a rarer medium. The figure shows that for a small angle of incidence, major part of the incident light is refracted and a small portion is reflected. The refracted ray ben..
Specific Rotation
Specific rotation refers to the rotatory power of a given solution. It is defined as the angle of rotation ( a -alpha) produced by one decimetre length of solution that has one gram of the substance per cubic centimetre. The measurement of rotation is carried out at temper..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
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
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
