Question

Simplify : SinA(cosecA-sinA)

Answer 1

Answer:

Step-by-step explanation:

SinA (cosecA-sinA)

=sinA (1/sinA-sinA)

=1-sin^2A

=cos^A

☺thank u☺

Answer 2

$SinA (CosecA-SinA) \\ wkt \: SinA = \frac{1}{CosecA} \\ SinA (CosecA-SinA) = SinA(\frac{1}{SinA} - SinA) \\ = 1 - {Sin}^{2} A \\ = {Cos}^{2}A$
hope it helps
