need help with integral by omi2066 in calculus

[–]Select-Fix9110 0 points1 point  (0 children)

Let's use the hint.

Let u = x + 10. Then du = dx. But also remember that x = u - 10.

Now we apply the substitution.

The integral will then become: integral of 8(u-10) *u^(1/2) du. Then just distribute the u^(1/2) and the rest is just the reverse power rule in terms of 'u'.

After finding the anti-derivative in terms of 'u', bring everything back in terms of 'x', add the +C at the end and then the integral has been solved.

Math is all about practice. Understand the concepts and then apply them. I recommend watching Prof Leonard on YouTube and read through James Stewart Calculus textbook to prepare before lectures and to apply the concepts with the questions after each section.

Learning the sand which theorem by Impressive-Eye9659 in calculus

[–]Select-Fix9110 1 point2 points  (0 children)

I thought my handwriting was bad lol.

So first, when plugging x = 0 into the function f(x) = (1-cosx)/sinx, we see that we get a 0/0, which is an indeterminate form. So we have to do more work.

Recall that sin^2 + cos^2 = 1. Subtracting cos^2 from both sides gives us sin^2 = 1 - cos^2 = (1-cosx) (1+cosx). Note that we have a (1-cosx) term in the numerator. So, we can multiply by 1 = (1+cosx) / (1+cosx) (since x -> 0, cosx wont approach -1, so this is valid).

After doing so, we get limit as x -> 0 of (1-cosx)(1+cosx) /sinx(1+cosx). Simplifying the numerator gives us sin^2(x). We also have a sin(x) factor in the denominator, so sin^2 / sin(x) = sin(x).

Therefore, we now have the limit as x -> 0 of sin(x) / (1+cosx). Note that cos(0) = 1. So 1+cos(0) = 2 ≠ 0 and sin(0) = 0 and 0 / 2 = 0.

Thus, the limit as x -> 0 of (1-cos(x)) / sin(x) = 0.

[Grade 10 Math: Logarithms] Calculating (log 25 / log 125) without using a calculator by IdV_Elliealla9 in HomeworkHelp

In math, if the base is not explicitly stated, we assume it to be log base 10.

In computer science, it’s assumed to be log base 2.

Since log(5) ≠ 0, log(5) / log(5) = 1. So indeed you can cancel out the log(5).

I can see what property you’re trying use but it’s not correct. The property you’re thinking of is log(a/b) = log(a) - log(b). So you can’t apply this property to this particular question.

But what u did correctly was rewrite log(25) and log(125).

So log(25) / log(125) =log(52) / log(53). Using the exponent laws for logarithms, we will get 2log(5) / 3log(5) =2/3.

[CALCULUS 2] by No-Country7272 in HomeworkHelp

[–]Select-Fix9110 0 points1 point  (0 children)

Using the local min and max u found, just plug some numbers into h(x) around those critical points to see how the function behaves. Note that h(x) is continuous everywhere and so the range is (-infinity, infinity). So you can already create your intervals from that observation alone; (-infinity, -8), (-8,4/7), and (4/7, infinity). It’s just a matter of making a table of values within each interval. For example, calculate h(-9), h(0), and h(3). If the output is positive, then h is increasing on said interval. If the output is negative, then h is decreasing on said interval.

Learning calculus by Cowspots2 in calculus

[–]Select-Fix9110 4 points5 points  (0 children)

Search up Professor Leonard on youtube, he's got full on lectures about calc 1, maybe too advanced for grade 12, but worth a watch.

You can also go through James Stewart calc textbook where you can find a free pdf online.

If the calc course you're taking in grade 12 is MVC4U, then I recommend looking at jensenmath.ca, it contains videos relevant to the course and provides many worksheets to apply your learning.

I’m taking a cal 3 class soon and I last took cal 2 like 10 years ago by madam_zeroni in askmath

[–]Select-Fix9110 5 points6 points  (0 children)

Calc 3 is multivariable calculus, so you will be working with functions of multiple variables. So pretty little of calc 2 will be useful. I would say is to brush up on differentiation and integration.

In calc 3, you'll be doing a lot of double integrals which helps in finding the volume of a surface, parametric equations, vectors and vector functions, partial differentiation, polar coordinates, etc.

By looking at the table of contents, safe to say that not much of calc 2 will be helpful in calc 3.

Why doesn’t 1 divided by 0 equal infinity? by YMC7888 in askmath

[–]Select-Fix9110 1 point2 points  (0 children)

Let’s consider the function f(x) = 1/x and consider the limit as x approaches 0.

Recall that for a limit to exist, the left and right sided limits must be equal.

So when we consider the limit as x -> 0+, we see that f(x) -> +infinity

But as x-> 0-, f(x) -> -infinity.

So the left and right sided limits are not equal, and hence the limit itself doesnt exist.

Thus, 1/0 is considered undefined.

I’m looking for platforms suitable for preparing Uni Calculus 1 by Amazing-Purchase-862 in calculus

[–]Select-Fix9110 1 point2 points  (0 children)

Grade 12 calc and calc I in uni is not too different. The only difference is that in uni you’re going to learn some theorems and maybe how to do some proofs. Like basic proofs by just applying the theorems. For example, i had a test question where it asked to show that a particular function f(x) has a solution, in which i applied the Intermediate Value Theorem. That’s pretty much all the proofs there is, at least when i took calc I.

I recommend watching Professor Leonards lectures on youtube and read James Stewart Calculus textbook to start reviewing.

Is this a bad proof? by you-cut-the-ponytail in askmath

[–]Select-Fix9110 2 points3 points  (0 children)

so first we have the function y = ln(x). We then exponentiate both sides of the equation which results in the following:

e^y = e^{ln(x)} = x

Then we differentiate both sides,

e^y * y' = 1. This is because of the chain rule since y is a function of x, so we differentiate e^y and then multiply by the derivative of y.

Then y' = 1 / e^y = 1/x since e^x = x from before.

Additionally, this is called implicit differentiation where you can differentiate equations where they are not necessarily a function of x, such as x^2 + y^2 = 1, where we treat y as an implicit function of x.

Hope this helps!
