The Gradient of the curve is different at every point so what is require here is the x coordinate or the y coordinate and the Eq of the curve
So the methoda calculating the gradient is
________________________________________

1)
substitute the value of x into the derivative of the curve (y prime) that will be ur gradient for the specific point on the curve
________________________________________

2)
find the value of x by substituting the value of y into the eq of the curve and then solve the quadratic eq u will get 2 values in here and u will decide which value will it be according to the situation

Try finding out the difference between the sequence and then if there is a common sequence then u can figure it out easily !
For common difference sequence of nos. go one term back from the first term given and then make the equation !
for eg,
1 3 5 7 9 11 13 .....
For the equation do this !
first see the difference its 2 between each term {n} so now u go one term back from 1 by minusing 2 from the first term !
1-2=-1
now we make the equation :
2n - 1


Also there is one other sequence in which each term has a different difference between each term !
For that u use a quadratic equation to help out !

Should Stats be given as a private subject ? Would it be helpful in years later ?

yEAH IF UR school isnt offering it and u want to give it then go ahead as it results in an extra A* but u have to see how good u are in maths and particularly stats !
i dont know abt future but i think it helps in A Levels !
