You may have seen in previous courses the statement "for angles theta near zero, sin theta can be approximated by theta." I first saw this in a physics class when we were talking about pendulums. This approximation of sin theta by theta was completely mysterious to me when I first saw it. (I hadn't had calculus yet.) The object in this discussion is to find out where this approximation comes from.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

answer: none of these answers are correct only the second half is
