We did this new mathematics thing in class today which I did not understand, it came under the topic of differentiation.(adsbygoogle = window.adsbygoogle || []).push({});

Firstly we were given the equation

f(x)=E^x

Then find the value of F(x) for x=0

F(0)=E^0

F(0)=1

therefore (0,1)

Then it said find the equation of the tangent at x=0

Which I worked out to be Y(tangent)=X+1 [I will call this equation t(X)]

Then it said draw up a table ranging from -.2 to .2 with increments of 0.05 for the equation

[f(x)-t(x)/f(x)]*100

Now my question is what the hell are we finding here??

Thanks in advance for any help.
