If the trigonometric point P(t) has co-ordinates (x, y) then cos q = x, sin q = y. The point P (x,y) on the unit circle can be written as P (cos q , sin q ). From the figure, OP 2 = OM 2 + PM 2 x 2 + y 2 = 1 Now we have the identity (cos q ) 2 + (sin q ) 2 = 1...

Summary - An angiosperm plant body is composed of two basic types of tissues namely meristematic and permanent tissues. Meristematic tissue is formed by undifferentiated, embryonic cells called meristematic cells. Meristematic cells are compactly arranged. They have thin cell wall abundant cytoplas..
Summary (Contd..)
>- A surface touching these secondary wavelets tangentially in forward direction at any instant gives the new (secondary) wave front at that instant. Using Huygenss principle, we can prove the laws of reflection and the laws of refraction on the basis of the wave theory. Superposition principle say..

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 was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Very good, Tutor was clear and guided me through the whole algebra problems
