He got psyched out from all the religious talk around him and worried about going to hell. That was why Peter wrote about changing from sin. He wasn't man enough like Judas.
Social sin
We write sin x * sin x = sin2 x
Peter is symbolically associating Christ to a lamb who is born white, with no blemishes at all. It is free from all discolorations (Sin) and as pure and clean as the driven snow.
cos = sqrt(1 - sin^2)
90+ whatever number is in form of sin.
Peter Hain has written: 'Changing for good - devolution'
Peter De Rosa has written: 'Christ and original sin' -- subject(s): Original Sin, Person and offices 'God our Saviour' 'Prayers for pagans and hypocrites'
No. The product of sin (ax) and sin (bx) cannot be represented as a single sin unless a and b are equal.
Humans do not have to sin, though it is in our nature (Romans 3:23), except for Christ Jesus (1 Peter 2:22).
sin = opp/hyp cos = adj/hyp tan = opp/adj

The Wikipedia article "Trigonometric identities" lists the following identity (in which I am simply changing variables): cos a sin b = (1/2)[sin(a+b) - sin(a-b)] Here, since the two angles are the same, this simplifies to: cos a sin a = (1/2)[sin(2a) - sin(0)] = (1/2)sin(2a)
