Answer 2

Answer:

6*r*cos(r^2)

Step-by-step explanation:

d/dr(3sin(r^2))

we know while differentiating the constants are taken out

over here 3 is a constant

so we can write the above equation as 3*(d/dr(sin(r^2))

we know differentiation of sin x is cos x

and differentiation of x^2 is 2x

so using chain rule

3*(d/dr(sin r^2))

=3*( cos (r^2)* d/dr(r^2))

=3*(cos (r^2) * 2r)

= 6*r*cos(r^2)

Hope you found this answer helpful. Pls mark as the brainliest :-)
