This is a video tutorial in the Education category where you are going to learn how to master inverse proportions in Algebra. Inverse proportions have a different rule; more means less or less means more. Let us understand this with an example. It took 175 minutes to drive to the cottage at 80 kmph. If we drive at 100 kmph instead, how long will it take? Here the speed of travel is more but the time taken to complete the journey will be less. So, this is a more means less kind of inverse prop...
This video tutorial is in the Education category which will show you how to evaluate a line integral along a straight line segment using the definition of the line integral. This video evaluates a line integral along a straight line segment using a parametric representation of the curve (using a vector representation of the line segment) and then integrating. A vector representation of a line that starts at r0 and ends at r1 is r(t) = (1-t)r0 + tr1 where t is greater than equal to 0 and lesse...
This is a video tutorial in the Education category where you are going to learn how to use and understand chemical equilibrium in Chemistry. This video answers a question about the contact process. This is a process by which sulphuric acid is made where they take sulphur, react it with oxygen to make sulphur dioxide and react it with more oxygen to make sulphur trioxide.

This is a video tutorial in the Education category where you are going to learn how to do fraction multiplication. Before multiplying two fractions together by multiplying across the numerators and the denominators, you should always try to cross cancel as your 1st step. For example in the problem, (-15/4) x (14/5), 15 and 5 will cross cancel to 3 and 1. Similarly, 14 and 4 will cross cancel to 7 and 2. So, what you will get now is (- 3/2) x 7. Also you should take care of the signs. In this ...
This is a video tutorial in the Education category where you are going to learn how to apply the 6th Law of Exponents. The 6th law of exponents says, to raise a product to a power, you can multiply each of its factors by the same power. For example if you have (acm) to the power x, that will be equal to the product of (a to the power x), (c to the power x) and (m to the power x). How is this done? (acm) to the power x is same as (a to the 1, c to the 1 and m to the 1). What we are doing is, w...

After about half an hour, fi...
This video tutorial is in the Education category which will show you how to solve single-step inequalities using the reciprocal. Let's solve the problem "negative 5/2 X is less than equal to negative 1/5". To solve for "X", we need to get rid of "negative 5/2". To do that, we multiply both sides of the inequality by the reciprocal of 5/2 and we need to keep the negative sign also. So, we multiply both sides by "negative 2/5". Whenever we multiply a negative to both sides of an inequality, the...
This video tutorial belongs to the Education category which is going to show you how to match exponential graphs. The video shows two graph sheets with three graphs marked A to F on each sheet and six equations. It starts off with matching the basic function, y = 2 to the power x. If you plug in zero for x, you get '2 to the power 0' which is 1. Hence, the equation becomes; y = 1. So, the graph that passes through y = 1 is the matching one. In the video it is graph A. You can watch the video ...
This video tutorial is in the Education category where you will learn how to use commas with restrictive and non-restrictive clauses.

For example, in the sentence "the students who did not wear uniforms were punished". Here "students" is the subject and "were punished" is the verb and the clause "who did not wear uniforms" is restrictiv...
In this Education video tutorial you will learn how to divide fractions with examples. For example let us divide 1/5 with 3/4. This we can do by changing the division sign in to multiplication sign provided we swap the numerator and the denominator of the divisor to get its reciprocal. The equation can now be written as 1/5 x 4/3. Now multiplying the numerators and the denominators, we get the answer as 4/15. So, you can see that division of fractions is the same as multiplication. You only n...
