Question

If Y =cos(x²+a²) then dy/dx​

Answer 1

Answer:

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

Step-by-step explanation:

$\red{\underline{Question:-}}$

If Y =cos(x²+a²) then dy/dx​?

$\red{\underline{Solution:-}}$

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
