ā« sin x - cos x/ sin x dx
x * x - 5x + 6The x is actually x squared. Whats the answer?
ln (e^(-x) + x e^(-x)) derivative 1 / (e^(-x) + x e^(-x)) * (-e^(-x) x ) how did they get (-e^(-x) x ) , was it the product rule or just a chain rule ? and not sure how they got the answer - x / x + 1 ...doesnt make sense thanks
