@cwrw238 y=theta(sin(lntheta)+cos(lntheta), just like the other problem, the 2nd part cos(lnth..) i apply the chain rule correct?

OpenStudy (cwrw238):

yes apply chain rule to sin (ln theta) and cos( ln theta)

OpenStudy (anonymous):

would i apply the product rule the the 2nd part tho?

OpenStudy (cwrw238):

you could first expand the function to give theta * sin (ln theta) + theta* cos (ln theta) and apply the product rule to each part

OpenStudy (cwrw238):

about the product rule - it applies when u have the product of two functions
