Trigonometry Summary
Summary - sine of an angle = cosine of its complement. If sin A = cos B, then A + B = 90 o . Trigonometric ratios of standard angles (i) sin 0 o = 0, cos 0 o = 1, tan 0 o = 0 (i..

Some Trigonometrical Identities
L.H.S. = cosec q - cot q = R.H.S. Prove that L.H.S. = 2 sec q = R.H..
L.H.S. = cosec q - cot q = R.H.S. Prove that L.H.S. = 2 sec q = R.H..See what our Users say :
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
