Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
SOLVE:
X(2X2 +1)=15
Let the function is F(x) = 2x3 + x -15.
F(x) is negative at x = 1 and positive at x = 2, so the root of the function lies between the interval (1,2).
By using the Newton-Raphson method, we approach one root of a function by iterative process. Let start the process with arbitrary initial value x0 =1.5.
According to the Newton-Raphson Method
For the next approximation, the other value is x1=1.9655 from the above calculation:
