TOPIC - 2: Inverse Trigonometric Function

ACTIVITY 2.1

OBJECTIVE
To draw the graph of sin x, using the graph of sin x and demonstrate the concept of mirror reflection (about the
–1
line y = x).

MATERIAL REQUIRED
Y Cardboard Y Graph paper Y Paper pins / thumb pins Y Adhesive
Y White sheet Y Pen or sketch pens Y Some threads Y Geometry box

PRE-REQUISITE KNOWLEDGE
1. Knowledge of trigonometric functions.
2. Knowledge of inverse of trigonometric functions.

3. Knowledge of mirror reflection.

PROCEDURE
1. Take a cardboard of dimensions 30 cm × 30 cm.
2. Paste a white sheet on cardboard with thumb pins or glue as shown in Fig. (a).
