In Cipher Block Chaining (CBC) mode, decryption is obviously the symmetric counterpart to encryption, because the inverse operations are used in the reverse order; but in Counter (CTR) mode, decryption is the same as encryption except that the plaintext and ciphertext blocks are swapped. Briefly explain why Counter mode is symmetric, despite this apparent contradiction.

Ответ:
d/dx (2 x^2 y + y = 2x + 13) 4xy + 2x^2 y' + y' = 2 4xy + y'(2x^2 + 1) = 2 y' = (2- 4xy)/(2x^2 +1)
ow we can use this in a linear equation for a slope Ty = -5x/8 +5(3)/8 +8/8 = -5x/8 +(15+8)/8 = -5x/8 +23/8 this will gives us an approximation at x=2.8 now
