Trigonometry is a really important chapter and there is no chance of skipping it.
First of all, you must be clear with all the ratios like
Sin theta = P/H (P= Perpendicular, H= Hypotenuse)
Cos theta= B/H (B= Base)
Tan theta= P/B
Cosec theta= H/P
Sec theta= H/B
Cot theta= B/P
Then you must remember the values of all the angles formed by these trigonometric ratios.
The most important part is proving the trigonometric identity. Solve a lot of those questions. One or two questions for the proving of identities will definitely come.
The three identities are:
1) Sin²∅ + Cos²∅ =1
2) Sec²∅ - Tan²∅ =1
3) Cosec²∅ - Cot²∅=1
All the best
