Lim x-0 3x²/(1-cos5x)
mylen [45]

The limit is presented in the following undefined form:

\displaystyle \lim_{x\to 0}\dfrac{3x^2}{1-\cos(5x)} \to \dfrac{3\cdot 0^2}{1-\cos(5\cdot 0)} = \dfrac{0}{0}

In cases like this, we can use de l'Hospital rule, which states that this limit, if it exists, is the same as the limit of the derivatives of numerator and denominator.

So, we switch

\dfrac{f(x)}{g(x)}\to\dfrac{f'(x)}{g'(x)}

The derivative of the numerator is

\dfrac{d}{dx} 3x^2 = 6x

Whereas the derivative of the denominator is

\dfrac{d}{dx} (1-\cos(5x)) = 5\sin(5x)

So, the new limit is

\displaystyle \lim_{x\to 0}\dfrac{6x}{5\sin(5x)} \to \dfrac{6\cdot 0}{5\cdot 0} = \dfrac{0}{0}

So, it would seem that we didn't solve anything, but indeed we have! Recall the limit

\displaystyle \lim_{x\to 0} \dfrac{ax}{\sin(bx)} = \dfrac{a}{b}

to conclude that the limit converges to \dfrac{6}{25} [/tex]

Pls help me with this
astra-53 [7]

Answer:

the third one!

Step-by-step explanation:

Because it says, the SUM of the number, x (or z I can't really see it well) and 1/2, you must add those two together:

1/2 + x

Then it says those two numbers equal to 4, so it would look like this:

1/2 + x = 4

Because you are trying to isolate, and solve for x, you must SUBTRACT 1/2 from both sides of the equal sign:

1/2  +  x  =  4

-1/2            -1/2

1/2 minus 1/2 would result 0, so there would be x by itself. and 4 minus 1/2 would be 3 and a half ( 3  1/2), so x would be  3  1/2

x = 3 1/2

Hope this helped. If this is incorrect please specify so I can help :)
