f'(x)=

• $\lim_{h\rightarrow0}\left(\frac{f\left(x+h\right)-f\left(x\right)}{h}\right)$

• $\lim_{x\rightarrow c}\left(\frac{f\left(x\right)-f\left(c\right)}{x-c}\right)$

• $\frac{\text{d}y}{\text{d}x}$

• an equation for the slope of the tangent line

If

 $f\left(x\right)=x^2+2x$  which of the following is the derivative of f(x)

•  $\frac{\left(x+h\right)^2+2\left(x+h\right)\ -\left(x^2+2x\right)}{h}$  

•  $\frac{\left(x^2+2x+h\right)-\left(x^2+2x\right)}{h}$  

•  $\lim_{h\rightarrow0}\ \frac{\left(x^2+2x\ +h\right)-\left(x^2+2x\right)}{h}$  

•  $\lim_{h\rightarrow0}\ \frac{\left(x+h\right)^2+2\left(x+h\right)-x^2-2x}{h}$  

Answer explanation

this is the limit definition of taking a derivative

 $\frac{d}{dx}\left(\frac{\sin x}{1+\cos x}\right)=$  

•  $\frac{\cos x}{-\sin x}$  

•  $\frac{-\sin^2x-\cos x+\cos^2x}{\left(1+\cos x\right)^2}$  

•  $\frac{1}{1+\cos x}$  

•  $\frac{-\cos^2x+\cos x+\sin^2x}{\left(1+\cos x\right)^2}$
