hi

Hi i need to know the soln. for the following integral..

exp-[(x-a)/b]dx...a and b are some numbers...
thanks

Solve it by substitution if u = (x-a)/b
 
  • #3
So answer would be -b exp[(a-x)/b] + C...
Is this correct!

This expression doesn't mesh with what you had up earlier. Do you have [itex]e^\frac{x-a}{b}[/itex] or [itex]e^\frac{a-x}{b}[/itex] ?

hi

I have e[-(x-a)/b]...
the soln. is -b*e[(a-x)/b] + C
i.e., -b*e[-(x-a)/b] + C.
i think both the soln. are correct!

Your answer is correct.
 
  • #7
one more

The soln. for a*exp[-(x-b)^2/(2c^2)] is...
a*sqrt(2c)exp[-(x-b)^2/(2c^2)]...
is this correct?

I don't think so. Indefinite Gaussian integrals do not have closed form expression.
 

FAQ: Solution for exp-[(x-a)/b]dx with a and b numbers

What is the purpose of solving exp-[(x-a)/b]dx?

The purpose of solving exp-[(x-a)/b]dx is to find the anti-derivative of the given expression. This will allow us to evaluate the function at different values of x and determine its behavior over a range of values.

What is the meaning of "exp" in the expression exp-[(x-a)/b]dx?

"exp" is a mathematical notation for the exponential function, which is commonly written as e^x. In this expression, it indicates that the function we are solving involves an exponential term.

How does the variable "a" affect the solution of exp-[(x-a)/b]dx?

The variable "a" acts as a constant in this expression and shifts the function horizontally. This means that the solution will be affected by the value of "a" and will result in a different function with a different horizontal position.

What is the role of "b" in solving exp-[(x-a)/b]dx?

The variable "b" acts as a scaling factor in this expression and determines the rate at which the function changes. A larger value of "b" will result in a steeper curve, while a smaller value of "b" will result in a flatter curve.

Are there any special cases to consider when solving exp-[(x-a)/b]dx?

Yes, there are a few special cases to consider when solving this expression. If the value of "b" is equal to 0, then the expression becomes undefined. Additionally, if the value of "b" is negative, it will result in a reflection of the function over the y-axis.
