Question

differentiate
$log( \sqrt{1 - \cos(3x ) \div1 + \cos(3x) }$
​

Answer 1

Answer:

Step-by-step explanation:

⇒log√1-cos(3x)/1+cos(3x),

⇒y=log(2sin²3x)/2cos²3x),

⇒y=log(√tan²3x)=log(tan3x),

⇒dy/dx=1/tan3x  sec²3x . 3,

⇒dy/dx=3(sec²3x/tan 3),

⇒dy/dx=3/4  (1/cos²3x)/(sin3x/cos 3x),

⇒3/4 . 1/(sin3x.cos3x),

⇒dy/dx=3/4 . sec3x . cosec3x is the answer.

If wrong answer sorry i tried my level best to answer.

HOPE IT HELPS YOU.
