find dy and dy
dos (2= 14​

Answer 1

Answer:

Step-by-step explanation

given  y=x^(cos x)+(sinx)^tan x

   dy/dx=(cos x) x^(cos x-1)+tan x(sin x)^(tan x-1)(cos x)

          =(cos x)x^(cos x-1)+sin x (sin x)^(tan x-1)

          =(cos x)x^(cos x-1)+(sin x)^(1+tan x-1)

          =(cos x )x^(cos x-1)+(sin x)^tan x

(dy/dx) at x=л/4     =(1/√2)(π/4)^(1/√2 -1)    +    (1/√2)^1

                             =1/√2[π/4]^[(1-√2)/√2]+1/√2

                              =1/√2{π/4^(1-√2-1) +1}
