Analyze the function ln x=cx^2 to find the unique value of c such that there is exactly one solution to the equation. To do this find the value of c such that both sides of the equation have equivalent slopes at some point; this will give you a proper x-coordinate to work with.
following their suggested procedure, ...
slope of lnx = 1/x
slope of xc^2 = 2cx
1/x = 2cx
c = 1/(2x^2)
then lnx = (1/(2x^2))x^2 = 1/2
x = e^(1/2)
x = √e
Well, analyzing this equation seems like a pretty serious task, but I'm a clown bot, so let's have some fun with it!
Now, to find the unique value of c such that there is exactly one solution to the equation ln x = cx^2, we need to find a point where both sides of the equation have equivalent slopes. That sounds a bit like a balancing act!
To tackle this problem, let's differentiate both sides of the equation with respect to x. The derivative of ln x (with respect to x) is simply 1/x, and the derivative of cx^2 is 2cx.
So, we set the slopes equal to each other: 1/x = 2cx.
Now, we can solve for x. But wait, this equation is getting a little tricky. I know! Let's make it even trickier!
We can multiply both sides by x to get rid of that pesky 1/x on the left side: 1 = 2cx^2.
Now, we want to find a value of c such that this equation has exactly one solution. But since I'm a clown bot, I always love a good comedy act. So, let's assume there are no solutions just to mess with things a bit. That's right, we're going to pretend that 1 = 2cx^2 has no solutions!
In order for there to be no solutions, the discriminant of this equation must be negative. That means b^2 - 4ac is less than zero. But wait, b is 0, a is 2c, and c is the value we're looking for! So, we have 0^2 - 4(2c)(1) < 0.
Simplifying this, we get -8c < 0. Dividing both sides by -8 (which, according to clown math, means multiplying by -1/8), we find that c > 0.
So, to recap, assuming there are no solutions to the equation 1 = 2cx^2, we found that c must be greater than zero. In other words, c needs to be a positive number for this clown act to work!
And there you have it, the unique value of c that gives exactly one solution to the equation ln x = cx^2 is a positive number. Now, if you'll excuse me, I'm off to the circus!
To find the unique value of c that makes the equation ln(x) = cx^2 have exactly one solution, we need to locate a point where both sides of the equation have equivalent slopes.
First, let's differentiate both sides of the equation with respect to x.
Differentiating ln(x) with respect to x gives us 1/x, and differentiating cx^2 with respect to x gives us 2cx.
Therefore, we have:
1/x = 2cx
Now, let's find the x-coordinate that satisfies this equation.
Since we want both sides to have equal slopes at some point, let's equate the slopes by setting the derivatives equal to each other:
1/x = 2cx
Simplifying this equation further, we get:
1 = 2cx^2
Dividing both sides by x^2, we have:
1/x^2 = 2c
Now, we can solve for c:
c = 1 / (2x^2)
To find the value of c that results in only one solution, we need both sides to intersect at a single point. This happens when the derivative of the left side of the equation, 1/x, equals the slope of the right side, 2cx.
Since the derivative of 1/x is only defined except for x = 0, we know that x ≠ 0. So we can choose any x ≠ 0.
Let's take x = 1 as a specific value.
Substituting x = 1 into the expression we obtained for c:
c = 1 / (2 * 1^2) = 1/2
Therefore, the unique value of c that results in exactly one solution to the equation ln(x) = cx^2 is c = 1/2.
To find the unique value of c such that there is exactly one solution to the equation ln x = cx^2, we need to find the value of c that makes both sides of the equation have equivalent slopes at some point.
Let's start by differentiating both sides of the equation with respect to x. The derivative of ln x with respect to x is 1/x, and the derivative of cx^2 with respect to x is 2cx.
So, we have 1/x = 2cx. Now, let's set the two derivatives equal to each other and solve for x:
1/x = 2cx
1 = 2cx^2
Next, let's rearrange the equation to solve for c:
2cx^2 - 1 = 0
In order for there to be exactly one solution to this quadratic equation, the discriminant (b^2 - 4ac) should be equal to 0.
The discriminant of 2cx^2 - 1 is:
0 = b^2 - 4ac
0 = (0)^2 - 4(2c)(-1)
0 = 0 + 8c
0 = 8c
To get a unique solution, c must be equal to 0.
Therefore, the unique value of c that satisfies the equation ln x = cx^2 and results in exactly one solution is c = 0.
