2 [3] = 8 can also be expressed as log [2] 8 = 3


Is this correct?
0.035 [x] = 2.74 Find x?

1. Re-express as a log which is log [0.035] 2.74 = x
2. Draw line
3. log 2.74__ = x

log 0.035

Or is this correct?

0.035 [x] = 2.74 Find x?

1. Log both sides
   log 0.035 [x] = log 2.74
2. Re-express to remove power

x log 0.035 = log 2.74

1. Make x the subject of the equation

x = log 2.74 / log 0.035

Derivative

What really is first derivative?
Is first derivative any thing to do with differentation? Explain.

Limits

What is Limits

Why is limits needed in maths

What is the purpose of limits with respect to graphs

Why is limits used in the delta process

Delta process

gradient = change in y
change in x

why then do I see gradient = lim change in y
∆h→0 change in x

What is the purpose of lim
∆h→0

Why is (x1, y1) always (x, y)

Why for (x2, y2) , x2 is always x + ∆h
What then is y2

In class we refer to a policeman, what is this policeman all about?

What is the denominator always and why?

What is the numerator always and why?

Why the numerator has to factorise to take out ∆h?

How can someone say where ∆h is substitute 0?

Logs

What really is logs?
Do you think this is an important aspect of maths?
How is logs related to exp?
What is the basic strategy in logs?

Missing students

A lot of students have not sign in and hence no comments from you.

Should I just give 0 / 10
You are to comment on each post.
If your comment is none of the relevant types, it should be viewed as none.

Next week I will post the student names or ids

Exponent

What is the purpose of exponent?
Is a quadratic an exponent?
It is said that everything in life involves some aspect of Maths, give some real life scenarios that involves the exponent aspect of mahs.
