Question

y= cos ( x^2 + a^2 ), find dy/dx​

Answer 1

Answer:

-Sin ( x^2 + a^2 ) ( 2x)

Step-by-step explanation:

Given:   y= cos ( x^2 + a^2 )

To find:  dy/dx​

Solution:  

dy/dx​ = d cos ( x^2 + a^2 )/dx

= -Sin ( x^2 + a^2 ) ( 2x+0).............( using chain rule) ( since a^2  and differentiation of constant is zero)

= -Sin ( x^2 + a^2 ) ( 2x) is the answer

please mark my answer as brainliest

Answer 2

Answer:

dy/dx = -sin x²+a² × 2x .....here a is constant (as not in function of x so i take it as constant )
