Exponential Functions : We'll begin by looking at the exponential function,
f ( x ) = a x
We desire to differentiate this. The power rule which we looked previous section won't work as which required the exponent to be a fixed number & the base to be a variable. That is accurately the opposite from what we've got with this function. Thus, we're going to have to begin with the definition of the derivative.
Now, the a x is not influenced by the limit as it doesn't have any h's in it and hence is a constant so far as the limit is concerned. Therefore we can factor this out of the limit. It specified,
Now let's notice as well that the limit we've got above is accurately the definition of the derivative of f ( x ) = a x at x = 0 , i.e. f ′ (0) . Thus, the derivative becomes,
f ′ ( x ) = f ′ (0)a x
Thus, we are type of stuck. We have to know the derivative to get the derivative!
There is one value of a that we can deal along with at this point. There are actually a variety of ways to define e. Following are three of them.
Graph f ( x ) = e x and g ( x ) = e - x . Solution There actually isn't a lot to this problem other than ensuring that both of these exponentials are graphed somewhere.

What is the determinant of a square matrix?
if 1/x+2, 1/x+3, 1/x+5 are in AP find x Ans 1/x+2,1/x+3, 1/x+5 are in AP find x. 1/x+3 - 1/x+2 = 1/x+5-1/x+3 => 1/x 2 +5x+6 = 2/ x 2 +8x +15 => On solving we get x
