Before I go, do we necessarily need a calculator for trigonometry?

If someone asks you how high is that wall and you answer

you might get a dumfounded look but if you say .8660254037844386 m he is more likely to understand.

In short if you really want to be a hands on experimentalist ( Mr. Hadron Collider ) you had better get some experience with numerical math and calculators - CAS.

Why can't they understand? I beg one question without calculators would take hours.

Sometimes a nice closed form is good and sometimes you need the decimal answer. That is at least one spot where the calculator can help.

I'm good with pythagoras theorem if that helps. I'm gonna start learning loci in two dimension.

I stand corrected. But that just makes it more likely that humans are to blame.
