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 !

thankyou!

i think this will help abt the rotational symmetry

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

 

[scouserlfc]

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 !

Just wanted to know if statistics is a weak subject to take in general.Can it help with medicine?

 

[snowbrood]

can anyone solve Q.5 of ex 13d D3 oxford mathematics

Medical and stats two different subs i dont think so !

can anyone solve Q.5 of ex 13d D3 oxford mathematics

in the figure AB is the diameter of the circle . if ADE=DCA and CBA=70 find FEB and then EFC

 

[scouserlfc]

I dont think the diagram is up to the standards doesnt FEB in it look like 90 !

 

[snowbrood]

come on buddy u have to prove how to get 90 in FEB u just cant look and find it out come on u gotta prove it... and i cant draw any better

 

[snowbrood]

u kw that FEB is 90 so how do you get it tell me please
