It is important to know rates of change in many fields. Derivatives appear often in physics and engineering. Accurate predictions are made using equations that employ derivatives. They are called differential equations.

Because that is the rule for polynomial derivatives. Add up the derivatives of each term. The derivative of a constant term (like -20 in your case) is zero. The derivative of a*x^n is n*a*x^(n-1)

Math, derivatives
f(x) = x + 2Cosx, find f ' (x) a) 2(x+cos x) b) x - sin x c) 2x + sin x d)2(x - sin2x) I got neither of these answers, since the 2nd part should be chain rule, right? f(x) = x + 2Cosx = x + 2(Cos x) then f '(x) = (2)(2)(cosx)(-sinx) My answer: f '(x) = 2x - 4cosxsinx If ...

Check this problem for me do I have negative sign right with the answer. -1(-1)+-5-5=-2/-10==-1/5 the one on top and the -1(-1) and on the bottom is -5-5. so check this answer for me. Please, Please

I recognized the pattern for derivatives by First Principles If f(x) = 2^x, then the derivative by First Principles at the point (2,4) would be Limit (2^x - 2^2)/(x-2) as x ---> 2 which is your starting expression So f(x) = 2^x and a = 2 check: lim (2^x - 4)/(x-2) as x ---&...

Find the derivative of: ln(2x/x+1) the answer is 1/x(x+1) but i can't seem to solve it that far. ln [2x/(x+1)] = ln 2 + ln (x) - ln(x+1) Add the derivatives of each term and you get 1/x - 1/(x+1) = [(x+1) - x]/[x(x+1)] = 1/[x(x+1)]
