Time for a Math Fairy Tale, right?

Have you ever heard a math fairy tale so far? If you answered "no" then now it is time for it. Get ready, sit comfortable and enjoy reading it!




It was; it wasn't. On one defining sphere there was defined a strong logarithm, who had as a daughter a beautiful function. Sinus x, as his daughter was called, was truly gorgeous. Her elegant curve was accentuated with the absolute value, which she liked to dress in; a huge frequency and beautiful amplitude also added to her grace on the sympathetically symmetrical sphere of values. While smiling, she cutely pursed the period (on her lips) and her slight cosine overbite was no disadvantage either.

The functions of the entire defining sphere lived happily and all acknowledged the strong logarithm as their Lord and Ruler. But one day, a terrible derivation settled herself close to the logarithmic ruler, where the king was residing. She terrorised the right hand and left hand surroundings, and derived everything that came into her path, until everywhere were only zeros left lying around. One day she sent a message to the king: "After a week passes, I will derive your daughter". And there was lots of sadness in the ring surroundings, until the king decided: "Sinusoid and a half of the defining sphere will receive the one who will get rid of that awful derivation for us".

Initially, many functions that wanted to meet with the enemy signed up. But days passed, and after the derivation's work were always left only zeros. Brave composite functions hurled their parameters at the derivation, quadratic functions wanted to take advantage of the parabolic shape of their graphs in the fight, but all succumbed. The exponential knight, who although he has thought that he is unbeatable by the derivation, did not meet with success either; she cold-heartedly derived him at the base y.

A nobleman Arcus von Sinus also learned about the king's offer. He was wiser than all others, and so he didn't go directly to the battle, but first sought out an old wise integral, who had enormous experiences in fighting with derivations. "You did a good thing to come to me", said the integral to him. I will give you three gifts, which will help you in the fight. First is an exponential shield. It is created with exponential functions with differing variables, and therefore it is very hard to derive it. My second gift is this integral sword. It is the only weapon that is capable of beating the derivation. The third gift is  his cyclometric amulet. It will always remind you to not forget to add the constant during the integration. And now go, and may determinant accompany you."

And the day came, when the beautiful princess Sin x was to be derived. Accompanied by light linear functions the princess walked to the lair of the terrible derivation. Suddenly, Arcus von Sinus came dashing on a fiery limit and called out: "Don't be worried beautiful Lady...Function. I'm here to save you", and he urged his limit to a gallop. And here is the derivation climbing out of its lair. She spotted the fighter and flared herself at him. But Arcus wasn't waiting, and he attacked with his integration sword, covering every attempt of the derivation with his exponential shield. Everywhere around were fluttering bloodied partial fractions and on the ground were lying paralysed internal functions. Finally, the derivation slid down on the ground. "And it's done" rejoiced Arcus von Sinus. But suddenly, the old wise integral with red moustache appeared in the exponential shield: "One moment, prince. The second derivation doesn't mean anything to you?" said he.

And really. The second derivation was already coming out of the lair and lashed (out) at the knight. And again battle, again fractions and elementary functions lay everywhere around.

But eventually the prince was finished with the second derivation also. Then he looked into the textbook. "No, the third derivation really doesn't exist", he relaxed, heaving a sigh of relief. And right away, happy functions were rushing to him and celebrated the victory over the derivation.

The old wise logarithm came and thanked him also. Then he asked Arcus, how he can pay his debt to him. "I am a valiant functional rule and nobleman Arcus von Sinus. Give me your daughter, beautiful Sin x, and I will be happy." So he got the princess and they had together a beautiful constant.

And if they didn't die, they converge until today.
