Question

$sin^2a = \frac{1}{ { csc }^{2} a }$
​

Answer 1

Step-by-step explanation:

$sin {}^{2} a = \frac{1}{cosec {}^{2}a } \\ sin {}^{2} a = sin {}^{2} a \\ becasuse \\ \frac{1}{cosec {}^{2}a } = sin {}^{2} a$

Answer 2

ANSWER

THE STATEMENT IS COMPLETELY TRUE

STEP BY STEP EXPLANATION

LHS= Sin²a

RHS=1/cosec²a

=1/1/sin²a (cosec a =1/sin a)

=1×sin²a

=sin²a

= RHS

I HOPE THE ANSWER IS CLEAR AND HELPFUL...... : ))
