Homework Statement
ln(X+1)=Sin^2(x) solve
The Attempt at a Solution
I can get three solutions 0, .964, 1.684 using the calculator. How do you solve this wo/ a calculator.
The solution to this equation is x = 1.078 or approximately 1.08.
To solve this equation, you can use algebraic manipulation and trigonometric identities to rewrite the equation as x = arcsin(sqrt(ln(X+1))). Then, use a calculator to find the inverse sine function of the square root of ln(X+1).
Yes, you can use a graphing calculator to solve this equation. Graph both ln(X+1) and Sin^2(x) and find the point of intersection, which will give you the solution for x.
Yes, there are two solutions to this equation in the given interval.
Changing the interval can change the number and values of the solutions. In this case, the interval (0,3) was chosen because it contains the two solutions, but using a different interval may result in no solutions or different solutions.
