Trigonometry without panic: five questions SEBA repeats every year

Look at the last ten years of the Class 10 paper and the same five shapes of question come back. Learn the shape and the marks follow.

1. Height and distance with one observer

Two marks for the diagram, two for the correct ratio, one for the arithmetic. Draw the diagram even when you are sure of the answer — it is a standalone mark.

2. Proving an identity

Work on one side only. Examiners deduct when both sides are manipulated towards the middle.

3–5. The rest

Angle of elevation with two observers, complementary-angle simplification, and the value table. Each of these is a two-step problem dressed up as a long one.

Print the revision sheet, cover the right column, and write the identities from memory once a day for a week. That is the whole method.
