Class day: march,4 2011

This day I personally liked that learning English in addition to beingmuch more añprendimos things about mathematics as it arrived atthe formula of the area, including super interezantes.
The task of that day was:1.wich is the formula for the area of the triangule with base b,and height h?2.write the equation of the a atraight line with slope m and passing through the point P(Xo,Yo)3. calculate the area under the tangent through the point P(1,1) of the hyperbola    y=1/x

1.-How do you calculate the slope of a curve?
R= I calculate the derivative of the function.

f(x)=x¬2

df/dx=2x¬2-1=2x

f´´(x=1)=2*1=2

• What is the slope at the origin?

R=the slope at the origin is zero.

 f´(x=1)=2*0=0

• What was the class about?

R=The class was about the derivative

• What was the name of the lesson?

R=The name of the lesson was "Rate of change"

2.-Calculate the area below the tangent line of the hyperbola?

A=2 for any point in the hyperbola

3.-What is the formula for the area?

A=1/2 b*h
