$( \cot(30) - \tan(60) ) - \sin(30) = ( \sqrt{3} - \sqrt{3} ) - \frac{1}{2} = 0 - \frac{1}{2} = - \frac{1}{2} = - 0.5$

пожалуйста переведите...

that guy Fred, he's a real top banana. The guy's out to lunch. He better be careful because real soon he's going to find himself eating humble pie. His ideas are ok on the surface, but when you start to look at them you realize that they're really Swiss cheese - not well thought out. He always expects us to fill in the holes and make him look good. We get everything he gives us done to a T, but he takes all the credit. It would be nice if, for once, he would give us time to develop something challenging that we can really sink our teeth into. At least it would be nice to get credit for all that we do to make him and our organization look good, but I doubt that will happen; he always wants the whole enchilada for himself. He is always dangling the carrot of private compliments in our faces, but we know they are insincere. He must think we are a bunch of cream puffs. Someday, we are not going to fill in the holes and he will get his pie in the lace. He'll be in a real stew and we won't be there to clean it up. Soon... He'll get his just desserts.
