**$$\small\text{ $ \sin{ ( 12^{12^{14}} \ensurement{^{\circ}} ) } \\ =\sin{ ( 12^{ 168 } \ensurement{^{\circ}} ) } \\ = \sin{ ( 216 \ensurement{^{\circ}} ) } \\ = -0.587785252292 $ }}$$**

I like that Heureka. I would not thought to have used the mod function for this. Thanks ;)

Why is your answer different from Happy's answer?

**sin(12^12^14)**

**Hi Melody,**

here is the solution from WolframAlpha:

I think, the argument (12^12)^14 is to big for our calculator. But the mod - function is correct and departs from the argument multiple from 360 degrees.

The formula is $$\sin(\alpha) = \sin(\alpha \pm n*360\ensurement{^{\circ}} )$$

Thanks heureka,

This post is not just for heureka

I am still a little confused. Is there a glitch in the calculator? Why wasn't happy's answer the same?

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{400}}^\circ\right)} = {\mathtt{0.642\: \!787\: \!609\: \!687}}$$

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{400}}{\mathtt{\,-\,}}{\mathtt{360}}\right)} = {\mathtt{0.642\: \!787\: \!609\: \!687}}$$

Okay so why was mod function necessary - was it just that the sine function could not handle an angle that was so huge?
