Trigonometry is that branch of mathematics which deals with the measurements of sides and angles of triangles. The figure obtained by rotating a given ray about its end point is called an angle. An angle is called positive if the direction of rotation of ray from initial side to ..
Summary
1. In the principle value branches, the following formulae holds: sin -1 (sin x) = x, cos -1 (cos x) = x, tan -1 (tan x) = x, cos -1 (cot x) = x, sec -1 (secx) = x, cosec -1 (cosecx) = x 2. If a is some constant angle, then - sin q = sin a q = n p + (-1) n a..
Summary
The angle elevation and the angle of depressions are the angles which the line of sight makes with the horizontal. The angle of elevation of A as observed from C equals the angle of depression of C as observed from ..

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!!!
Very fast and clear. Made sure I understood the concepts instead of giving the answers to 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.
Looking for More Help!
