Question

Sin 2A = 2 Sin A is true when A: *
0 degree
30 degree
45 degree
60 degree​

Answer 1

Answer:

As we know that,

→ $</em></strong><strong><em>sin2A</em></strong><strong><em>= 2sin</em></strong><strong><em>A</em></strong><strong><em> </em></strong><strong><em>CosA</em></strong><strong><em>$

If,

A=0° Then,

→ $</strong><strong>cos0°</strong><strong> = 1$

From this,

→ $</strong><strong> sin2A</strong><strong> = 2sin</strong><strong>A</strong><strong> </strong><strong>cosA</strong><strong>$

→ $</strong><strong>sin</strong><strong>2</strong><strong>(</strong><strong>0°</strong><strong>)</strong><strong>= 2sin0</strong><strong>°</strong><strong>cos0</strong><strong>°</strong><strong>$

→ LHS=RHS

$sin2A = 2sinA cosA$
