Video Tutorials for Math

Introduction about video tutorials for math:

Math is very interesting and complicated subject. We have various types of method and procedures to solve the math question. Tutorial is one of the techniques to improve the student’s knowledge. Students can learn their own speed, and their convenience. Interactive classes can do by a tutor during tutorials. One of the main benefits is, students clarify their doubts frankly as well as immediately. Here we are going to learn about some example problems of tutorials for math.

Having problem with Derivative Product Rule keep reading my upcoming posts, i will try to help you.

Example problems of video tutorials for math:


Example 1:

A train takes to travels 200 miles in 4 hours. How long the train travels in 8 hours?

Solution:

Step 1: We know that the train travel 200 miles. If a train travel 8 hours how many miles the train travel?

Step 2: it’s the direct proportionality.

Step 3: We know that

Hour’s         miles

4               200

8                 x

Step 4: Now we need to solve the value of x using cross multiplication. So, we get 4x= 1600

Step 5: Divide using 4 on both the sides. So, the train travelled 400 miles.

Example 2:

Using these lines. Find the intersecting points?

y = 2y+2

y = x+12

Solution:

Step 1:

y = 2x+2      ------------> ( 1 )

y = x+12      -------------> ( 2 )

Step 2:

We know that the two lines are equal. So, it can be written as ,2x + 2 = x + 12

Step 3:  Here we need to solve the value of x. So, 2x – x = 12 – 2.Therefore, the value of x is 10

Step 4:

Substituting the value of x=10 in equation (1)

y = 2x + 2

= 2 ( 10 ) + 2

= 20 + 2   = 22

y = 22

The two given two lines intersect at a point (10, 22)

This is the example of intersecting lines.

One more example of video tutorials for math:


Example 3:

The sum of the least and greatest of 3 consecutive integers is 160. What are the values of the 3 integers?

Solution:

Step 1: Let us assume the integers are x,x+1 and x+2 .

Step 2: And we know that , the least and greatest of the 3 consecutive integer is 160 .

Step 3: So, we can arrange the equation, that is x+(x+2) = 160 .

Step 4: Here we need to solve this equation. So 2x+2 = 160. (Subtract 2 on both the sides)

Step 5: Therefore x= 79. Therefore the least integer is 79.

Step 6: Substitute the x value is x+1, x+2 .

Step 7: Therefore, 79+1 = 80 and 79+2= 81.

Step 8: Therefore, the values of 3 integers are 79, 80 and 81.
