how do i find dy/dx? where y = cos (xy^2) could i say dy/dx = -sin (xy^2) times the derivative of the inside stuff? with respect to x. i suppose i would use the product rule? right or is there an easier way to do this problem?
How do i find
Could i say: . .times the derivative of the inside stuff with respect to x? . Yes!
i suppose i would use the product rule, right? . Right!
or is there an easier way to do this problem? . I don't think so.
You'd have: .
Then solve for . . . carefully.
