Dear Student,

sin 2A is defined as 2 sin A cos A for any angleSo, for A=0 alsosin 2A=2 sin A cos AWhich meanssin 2A=2 sin A is not correct for A=0you can claim that the value of LHS and RHS at A=0 is same(i
e  0) so, it should be correct
but sin 2A=2 sin A is an identity not valuethat's why it is incorrect
