Using a limit of slopes, find the slope of the tangent line to y=sin(x) at x=c?

then solve for the values of c where the tangent slope is zero. Explain why this makes sense graphically.





your help is greatly appreciated thanks!

Using a limit of slopes, find the slope of the tangent line to y=sin(x) at x=c?
slope of the given curve is dy/dx=cos(x) at x=c,slope is cos(c)


for the tangent slope to be zero, cos(c) must be equal to 0.


so cos(c)=0 this implies c=(2n+1)pie/2 n=0,1,2,3.......
