Trignometry is easy to learn.Follow these:
first of all solve questions based on triangles,draw some right-angled triangles.
solve questions based on pythagoras theorem.
Solve questions in which one of the trignometric ratios (sin,cos...etc)is given and you will have to find other ratios.
Learn to prove trignometricidentity(formula)
sin^2(A) + cos^2(A) =1 and others.
