In physics it is important to use mathematical approximations. Demonstrate that for small angles (<20^∘), tanα≈sinα≈α=(πα^')/(180^∘) where αis in radians and α^' is in degrees. Use a calculator to find the largest angle for which tan αmay be approximated by αwith an error less than 10.0%. | Numerade
