Question

Q 3A Complete the following activity with the help of adjoining figure. 2
sin x =
cosec x =
A
sin x x cosec x =
X
x
B​

Answer 1

Step-by-step explanation:

According to fig,

Sin x = opposite/ Hypotenuse = AB/ AC

Cosec x = 1 / Sin x = 1 / AB / AC = AC / AB

$\sin(x) \times \csc(x) = \frac{ab}{ac} \times \frac{ac}{ab}$

then ab ab will be cancelled.

also ac ac will be cancelled.

hence,

$\sin(x) \times \csc(x) = 1$
