exponentials

I don't get all this question
A and B
Why do u differentiate and what does B mean

Why does d turn into Pi

[shut latch]

In an AP the difference is the difference between the 2nd term and 1 St term or 3rd term and 2nd term and so on

Also tan(x) has a period of 180 degrees so the d is pi

Free 9 marks icl but was something different nice to see

[ivory salmon]

So how do u find the difference between 1 and 2 twrm and 3 and 4 term

[ivory salmon]

What's d

[shut latch]

D is difference

[shut latch]

Term 2 - term 1

Term 4-term 3

But I don't it's enough to state that the difference between these terms of pi because how do uk that the next terms will have the same difference

But we know that tan repeats every pi so the next term has to be pi greater than the pervious term

[ivory salmon]

Omg that makes sense now 😂

[ivory salmon]

Ohhh

Understood that

[ivory salmon]

What about the geometric one

Wait so do u find the y coordinates from the x and then

Put it into a sequence and show there is a r

[shut latch]

Yep

[shut latch]

Yep

To find r just do 2nd term divided by 1st term

3rd term divided by 2nd term and soo on

[ivory salmon]

Ohh got it 👍

[shut latch]

Think u kight have to do that for every term tho bcuz we have to show the ratio is the same throughout

[ivory salmon]

O

[shut latch]

In the mark scheme it doesn't but we don't know that when solving the question also it's 9 marks so I would have done that
