Good day Engineers,may i get help with this differentiation problem: y=sec(3x^2+2x)

 

Use the chain rule.

 

Thanks a lot Sir

 

Maybe this will help.

and you still need to use the chain rule

 

Thanks a lot Papabravo

 

or go to Wolfram Alpha and type:

differentiate y=sec(3x^2+2x)

it will also show step by step if you like...

 

Many thanks to you Panic Mode.
