**Derivative Of Sin 2x**

Find W Sin2x Derivatives?

Can you help me find the Sina 2 derivative? I know this is equivalent to 2cos2x, but I don't know which step to use. The Chinese rule can't be used, just add sign 2x = 2 syncs and cast 2x = cos 2x x 2x..thanks!

updateThanks for posting .. Now I have to do this (2x) = 2x2x with Idens Cast 2x = Coxscocks Cinxxx and Sino2x = 2xxxxx. The NO China rule still exists. Thank you very much!

You have indicated that the Chinese rule should not be used.

Applies to the following: f (x) = cos 2x = 2 sinxcosx

Use the yout roll: f (x) = d (2 syncs) / dx

= 2 (synx) + coxs (coxs))

= 2 (x square sin for square sin)

= 2 cases 2x
