If sin 0

find the values of cose and tan by completing the

25

following activity.

7

sin =

...(i) (Given)

25

Consider AABC, where ZABC-90° and ZACB=0.

sin e

...(ii) [By definition)

7

25k

7ki

...[From (i) and (ii)]

25

B

Let AB 7k and AC -25k

In AABC, ZB = 90°

AB? + BC = AC? ...[Pythagoras theorem)

BC - D

Now, cos e

BC
