sine tables, that's how they did it before calculators, there are formulas as well
The exact value of (\cos(40.7^\circ)) is not a simple rational number or a well-known trigonometric value. To find its numerical approximation, you can use a calculator, which gives (\cos(40.7^\circ) \approx 0.7578). For precise applications, it's best to use a calculator or software that can compute trigonometric functions.
To find the exact value you could:use exact values rather than estimates - as inputs;use exact formula instead of approximations,use calculus.There are other methods as well and the choice depends on the circumstances. Then, if Y is your value and E is the exact value,percentage error = 100*(Y - E)/E or 100*(Y/E - 1).
It depends on the exact value of h, but, algebraically, the answer is h/24.

The exact value of sec 4pi divided by 3 is 1/3.
Yes. It does not have to be an exact value.
Use estimates and see if the calculation gives an answer that is similar to the exact calculated value.
The circumference of any circle when divided by its diameter has the exact value of pi
700 - 320 = 380. The exact value, which is easy enough to calculate rather than waste your time with estimates and then worry about errors and so forth, is 378.700 - 320 = 380.

1/squareroot2 ummm, yes, but be aware that square root 2 is an irrational number that has *no* exact value. So your question cannot be answered in the terms you asked it. You can use a calculator to get as much precision as you want, but never an *exact* answer.
