You would make the fractions improper, multiply then simplify. The answer is 10. (:
The domain of the function y=tan(x) ) is all real numbers except the values where cos(x) is equal to 0 , that is, the values π/2+πn for all integers n . The range of the tangent function is all real numbers.
You can write it as 0.35 or 35/100
Hope this helps :) If you need anymore help just let me know :)
