Hello, please help, I enter such an expression tg (sin (1) / sin (2)) + 2 ^ ctg (cos (2)) - 1 / (2 * 3) +3, writes the error what to do. thank you in advance.

 

Дорогой друг, доброе утро!

 

tg (sin (1) / sin (2)) + 2 ^ ctg (cos (2)) - 1 / (2 * 3) +3

\(\frac{tan\ sin(1)}{sin(2)}+2^{cot(cos(2))}-\frac{1}{2\times 3}+3\\ =\frac{tan(0.8415)}{0.9093}+2^{cot(-0.4161)}-\frac{1}{6}+3\\ =\frac{1.1190}{0.9093}+2^{-2.2629}-\frac{1}{6}+3\\ =1.23055401916+0.208388277823-0.1\overline6+3\\ \color{blue}=4.27227563031\)
