This is cal 1, and man, I feel like I suck. I need to find dy/dx (derivative of y with respect to x, yeah?) of
y = xe^-x*secx
What rule do I use? If the rule isn't applicable do I just "take the derivative"? like cosx is y'=-sinx what rule is used :???:
For example in this problem,
y = 4tanx*secx - csc^2x
What rule is used? For csc^2x would I use the chain rule? And 4tanx*secx a different rule? I would think to use the difference rule, but I cant because "4tanx*secx"?
And just as a general question, do some derivatives involve say the product rule and then the power rule?
