# Math Induction Question watch

1. I never got taught math induction, but here is the q i got:

For an equation , where n is positive integers:

• area B is the area under the curve from x = a to b and the x axis; and can be found the with equation
• area A is the area from to and the y axis; and can be found with the equation

Using mathematical induction, prove that the ratio of area A:area B is always for all positive integers, as a, b and n vary

How/What exactly would you do?
2. Surely Area A : Area B = = 1:n, so the statement is false?
3. (Original post by James)
Surely Area A : Area B = = 1:n, so the statement is false?

mixed the A and B up, it is infact A = and B \

therefore, n:1
4. not induction just A:B = n/(n+1):1/(n+1)= n:1
5. Thats what i thought but the question says use induction as a, b, n vary
