Sin 4

Sin is described in the Bible as transgression of the law of God ( 1 John 3:4) and rebellion against God ( Deuteronomy 9:7; Joshua 1:18 ). Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. ∴ sin−1 sin4 = sin−1(−sinx) = −x = −(4−π) =(π−4) This identity simplifies the given trigonometric expression by factorising it as product of two factors.g. So assume a = cos2x cos 2 x and b = sin2x sin 2 x then we get, ⇒ (cos2x)2 − (sin2x)2 = cos4x −sin4x ⇒ ( cos 2 x) 2 − ( sin 2 x) 2 = cos 4 x − sin4 x = (sin2 x)2 sin 4 x = ( sin 2 x) 2.
