Any transformation I perform to it … As x approaches 0 from the negative side, (1-cos (x))/x will always be negative. Tan x = sin x. View Solution. Apply L'Hospital's rule. lim_ (x->0)2tan^2x/ (x^2) = 2 Considering that: tanx=sinx/cosx We have that: 2tan^2x/ (x^2) = 2* (sinx/x)^2*1/ (cos^2x) So: lim_ (x->0 I'm not sure how to evaluate this limit. Use l'Hospital's As x approaches 0 from the negative side, (1-cos (x))/x will always be negative. We know that the function has a limit as x approaches 0 because the function gives an indeterminate form when x=0 is plugged in.1. Given limit is L = lim x→0 (xtan2x−2xtanx) (1−cos2x)2. In numerator, you may use series expansion of tan x = x + x3 3. y → 0. jika kita melihat seperti ini maka kita harus juga bentuk Sin X + Sin 3x dengan menggunakan rumus sin a + sin b = 2 Sin setengah a + b dikali cos setengah A min b tinggal di sini X + Sin 3X = 2 Sin setengah X per 3 X dikali cos setengah x 3 x = 2 Sin 2 X dikali cos min x kita tahu di sini cos x = cos X sehingga dapat kembali = 2 Sin X dikali cos X sehingga dapat kita tulis kembali disini therefore the above equation is equal to.
