In physics it is important to use mathematical approximations. Demonstrate that for small angles (< 20°) the following relationship is true where α is in radians and α' is in degrees.tan(α)~= sin(α) ~= α = (pi*α')/(180 deg)Use a calculator to find the largest angle for which tan α may be approximated by α with an error less than 10.0%.α' = ????
