Now, how would we tackle this? Well, I, here, I would do the product rule first. So let's do that. So let's do the product rule. So we're gonna take the derivative of the first expression. So derivative of x to the sixth is six x to the fifth times the second expression, sine to the third of x, or sine of x to the third power, plus the first x to the sixth times the derivative of the second, and I'm just gonna write that, d dx of sine of x to the third power. Now, to evaluate this right over here, it does definitely make sense to use the chain rule, use the chain rule.
