Question

what is derivative??

Answer 1

A derivative is the slope of the tangent line to the graph of a function at a value of x or the instantaneous rate of change of y with respect to x

Answer 2

hmmm

Answer 3

can you give me some examples?

Answer 4

if function is y = x^2 the slope of its tangent at pt (x,y) is 2x
as dy/dx = 2x, dy/dx is the derivative of y wrt x...

Answer 5

get it?

Answer 6

yea so so

Answer 7

see actually derivative means the ratio of change in dependent variable to change in independent variable...dy/dx

Answer 8

ahh now got it ^^

Answer 9

so can you give another numeric example?

Answer 10

Slope of tangent to curve y = 3x^2 at (1,3)
dy/dx = 6x
slope = dy/dx = 6(1) = 6

Answer 11

Ahh ok ^^ thanks much ^^

Answer 12

himm how old are you(interested in ppls age :))

Answer 13

18

Answer 14
