3 WAYS TO SOLVE LIMITS
Solving limits is a key component of any Calculus 1 course and when the x value is approaching a finite number (i.e. not infinity), there are only a couple techniques we need to learn in order to solve them. In this video Mike walks through examples for the three main techniques:
- Factor & Cancel
- Multiply by the Conjugate
- Common Denominator

Students Celebrate Pi Day 2019
zhlédnutí 418Před 5 lety
We asked some of our students what their favourite flavour of pie was, how many digits of Pi they could recite, and what they knew about Pi to celebrate Pi Day 2019. As a reward, we fed them delicious pie in our office! Happy Pi Day from all of us at Arnold Tutoring!
How Ontario High School Math Tests are Graded

Ever wonder what those letters stood for at the top of a high school math test in Ontario? Mike breaks down the difference between K/U, A, T, and C and what types of questions would fall into each category.

Characteristics of Rational Functions
zhlédnutí 80KPřed 5 lety
Mike explains the important characteristics found in rational functions. A rational function is defined as a fraction with a polynomial in the numerator and a polynomial in the denominator. X-Intercepts: Found at x-values that make unique factors in the numerator zero Vertical Asymptotes: Found at x-values that make unique factors in the denominator zero Holes: Found at x-values that make commo...
What is ln?
zhlédnutí 131KPřed 5 lety
Ln or "lawn" is the Natural Logarithm which works just like any other log you've learned about, only the base of the natural logarithm is euler's constant (e). It's often used in questions that involve population growth, bacterial growth, or decay. Don't get intimidated by this two-letter concept, if you understand logarithms, you're good to go!
Arc Length of a Circle
zhlédnutí 684Před 5 lety
Mike explains how to find the arc length of a segment of a circle based on its radius and central angle. It's crucial to convert the central angle into radians if it's provided in degrees. This is especially helpful for the Manitoba 40S Pre-Calculus Provincial Exam. Students can find our online course covering every topic on the exam at arnoldtutoring.teachable.com/p/40sprecalculus/
The Unit Circle Explained
zhlédnutí 381Před 5 lety
This video breaks down how the unit circle works, how we can think about x and y in terms of sine and cosine, and how we can draw the terminal arm within the circle to create easy to use triangles. We also discuss how to determine whether or not a point lies on the unit circle. This video is part of the 40S Pre-Calculus Exam Prep Seminar offered here: arnoldtutoring.teachable.com/p/40sprecalcul...

Symmetry of the Normal Distribution
zhlédnutí 7KPřed 5 lety
You only need to know information about one side of the Normal Distribution because of the symmetrical properties. The area to the left of the mean is identical to the area to the right of the mean. We also know that the total area under the curve must sum to 1 (i.e. 100% probability). The symmetrical property is even more important to understand depending on the Standard Normal Table you're de...

General Solutions of Trig Equations
zhlédnutí 823Před 5 lety
When the domain of your variable is not closed (eg. element of the reals) we need a general solution to cover every possible angle that makes the equation true. First step is to solve the trig equation and determine the solutions in the first rotation of the unit circle (between 0 and 2pi). Then you want to provide a general solution where you add multiples of pi or 2pi to hit every possible an...

Vectors: Using Projections to Find Component Vectors
zhlédnutí 176Před 5 lety
This video shows how projections can be used to find the magnitude of component vectors that make up a particular resultant vector. This is helpful, especially when the component vectors aren't along the traditional x and y axes. Note that this solution could be much simpler by just drawing the two right-angle triangles from the projections, and jumping right to Fcos(theta) for each one. Howeve...

    Thank you so much. I hate that my course doesn't actually cover this, but then asks questions in the homework about it. And my teacher frequently has said; "The homework questions make you apply what you've learned," but basically all I hear is "we enjoy that you struggle by us not actually explaining how to use the tools we give you." So THANK YOU for actually showing us how to use our tools.

    Good afternoon, sir. I have a worry and that is when you expand the parentheses of (x-5) and root of (x+4)+(3) you will end up having 3 as your answer but when you just cancel out without expanding the parentheses, you will end up having 6 as your answer. If you could please clarify that for me, thank you!

    Good work, could I say when a function itself is not able to produce output at a specific input and it haults the operation at a specific x value. To overcome this situation we take help from the limit and limit helps us to take out of this situation. After calculating the limit value we GIVE THIS VALUE TO THAT FUNCTION WHICH WAS Not PRODUCING ANY OUTPUT AT SPECIFIC INPUT??? iF THIS IS THE CASE THEN can say that function and limit both are different BUT it is the limit which helps the function which was trapped on a specific value and now because of limit function is able to walk smoothly again?? In a result could I say that whenever a function trapped in an undefined situation, we have to bring in LIMIT at this point?? please help me out! thanks.
