What Is a Linear Approximation Calculator?
At its core, a Linear Approximation Calculator is a digital tool designed to assist in finding the linear approximation of a function. Linear approximation is a technique used in calculus to find a tangent line that approximates the function at a given point. By using the linear approximation, complex functions can be simplified to linear functions, which are easier to work with. This approximation is primarily based on the formula:
[ L(x) = f(a) + f'(a)(x – a) ]
Where:
- ( L(x) ) is the linear approximation of the function
- ( f(a) ) is the value of the function at point 'a'
- ( f'(a) ) is the derivative of the function at point 'a'
- ( (x – a) ) is the change in x from the point of tangency
