Question

if sinA A =1/2 then the value of cosec²A is​

Answer 1

Answer:

Sin A = 1 / 2 = p / h

or , cosec A = h / p

or , 2 / 1 = 2

or , cosec²A = (2)²

= 4

Answer 2

4

Step-by-step explanation:

QUESTION :-

If sinA = 1/2, then the value of cosec²A is

_____________________

SOLUTION :-

We know that,

sin inverse = cosec

$\bf = > \sin A = \frac{1}{ \cosec A}$

Given that,

sin A = 1/2

$\bf = > \frac{1}{2} = \frac{1}{ \cosec A} \\ \\ \bf = > \cosec A = 2 \\ \\ \bf so \\ \bf{ \cosec }^{2} A = {2}^{2} = 4$

Hence,

cosec²A = 4
