Why shouldn't you eat in a chemistry lab area, even when there is no lab?

In addition to the first response, you should never eat in
a chemistry lab simply because those are the rules. I have worked in many science labs
and they all had stated "no food or drink allowed".


For
example, thermometers are frequently used in labs. Thermometers are fragile and break
often. They contain mercury which is very lethal when ingested. If you place food near
on mercury that may have spilled on the counter top and then you eat that food you may
become very ill.


Other chemicals that spill may also leave
residue that may linger for some time.

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
