Ex 12.1, 17 Evaluate the Given limit: lim┬(x→0) cos⁡〖2x − 1〗/cos⁡〖x − 1〗 lim┬(x→0) ( cos⁡〖2x 〗− 1)/cos⁡〖x − 1〗 = lim┬(x→0) ((1 − 2 〖sin^2〗⁡x) ... 1 - cos x sin x = sin x 2 cos x 2 ⇒ 1 - cos x sin x = tan x 2 Hence, the formula for 1 - cos x sin x is tan x 2. The derivative of 1/cos(x) is tan(x)sec(x). This can be found using the quotient rule, or through trigonometric identities, since 1/cos(x) = sec(x). Free Trial Available!

Solution: We have, (1+cosx)(1+cosy)(1+cosz)=(1-cosx)(1-cosy)(1-cosz) Multiplying both sides by (1+cosx)(1+cosy)(1+cosz) we get
