Answer and Explanation: 1 ... Given: The function is f ( x ) = tan ⁡ 2 x x , x ≠ 0. ... Thus, the limit lim x → 0 ⁡ tan ⁡ 2 x x is 2 . ... Given: The function is f ( ... Þ ¼ 1 þ tan 2 x tan π. 4. ¼ 1. The first derivative of a function is defined as follows: lim x⟶x0. f xð Þ - f x0 ð Þ x - x0. Therefore, the value of the ... Nov 19, 2019 ... sin(2x) = 2 sin(x) cos(x) = 2 (-8/17)(15/16) = -240/289 cos(2x) = 1 - 2* sin^2(x) = 1 - Feb 16, 2017 ... Here are four ways to prove this. You need to know cos2x+sin2x=1 cos 2 x + sin 2 x = 1 and sec2x−tan2x=1 sec 2 x − tan 2 x = 1 .
