Differentiate cos x w.r.t. e^x.

Please answer with proper steps

Dear student

 

first differentiate cos x w.r.t. x

 

 d(cos x) /dx = – sin x

 

differentiate e^x w.r.t. x

 

d(e^x)/dx = e^x

 

now d(cos x) / d(e^x) = – sin x / (e^x)

Hello, friend, try this method

        let, y=cosx

               

 

                      

                      

                       

                         Answer.
