curve sketching

Let us learn about curve sketching

Sketch the curve
y = - sin 2x ….(1)
Symmetry

(a) By replacing y by -y, the equation (1) is altered; so the curve is not symmetrical about x-axis.

(b) By replacing x by –x & the equation of the curve is altered; so the curve is not symmetrical about y-axis.

(c) Replace x & y by -x and -y respectively in the equation y = - sin 2x, the equation of the curve remain unaltered. So the curve is symmetrical in opposite quadrants.

The term “curve sketching” referred as using calculus to help draw the graph of a function by hand – the graph was the goal. Hence graphs can now be produced with great precision using computers & calculators.

matrix properties

Let us learn about matrix properties

The invertible matrix properties represent the properties which explain the matrices that are invertible that is which matrices are compatible to find out the inverse of the matrix in detail. Some properties involved in the invertible matrix are mentioned below

• The invertible matrix must be square - matrix.
• The invertible matrix must be the non - singular matrix.
• The determinant value should not be “0” zero.

hypotenuse calculator

Let us solve problem using hypotenuse calculator

The Hypotenuse Calculator makes it simple to find the length of any hypotenuse

The hypotenuse calculator can be found using the Pythagorean Theorem which states that a^2 + b^2 = c^2. Square the 2 sides add them together then find the square root to calculate the hypotenuse. A hypotenuse is referred as the side of a right triangle opposite the right angle

Use hypotenuse calculator to find the hypotenuse of the triangle when the 2 sides are a=8cm & b=6cm

Right angle triangle

a=8cm & b=6c, if we substitute the side values a & b in the calculator, then we get the hypotenuse value.

Using Pythagorean Theorem, we have to use hypotenuse calculator to find the hypotenuse.

: a² + b² = c²

8² + 6² = c²

64+36= c²

100= c²

C=10cm

Therefore the hypotenuse of the triangle is c=10cm.

math homework help for free

Let us learn about math homework help for free

Math homework help for free gives us the opportunity to practice what we are learning in class. When we do Math homework we learn which skills we don't fully understand. We can also discover new ways & methods of approaching a problem. Math Homework does not just aid our learning it also helps us study for those inevitable tests & quizzes which do determine our grades.

Math Homework has been a part of students' life from the beginning of formal school. However, the practice has sometimes been accepted & other times rejected, both by parents & educators. This has happened because Math homework can have both negative & positive effects on learner's learning & attitudes towards school. Some tutors view that math homework should not be given to students. Giving Math homework means creating learning environment like school mania at home. Others educators are of the view that five hours in the school is in sufficient & it must be supplemented by some work at home. It is not the math homework that is objectionable, but its nature & amount which invites criticism. But the importance & need of math homework cannot be minimized, if it is of a right nature.

slant asymptote

Let us learn about slant asymptote

Try to find the slant asymptote of the following function:

Y = x² + 3x + 2 divided by x – 2

To find the slant asymptote, we need to do the long division:

The slant asymptote is the polynomial part of the solution, not the remainder.

Slant asymptote: y = x + 5

Just like horizontal & vertical asymptotes, slant asymptotes are lines the graph approaches. Slant asymptote are also called oblique asymptotes.

A graph always has a slant asymptote if the degree of the numerator is bigger than the degree of the denominator

If you want to find slant asymptotes, divide the numerator by the denominator & keep only the quotient Don't forget that these are still lines, so slant asymptote are written as y =

To divide slant asymptote, you either have to use long division or synthetic division

multiples of 9

Let us learn about multiples of 9

The multiples of a whole number are found by including the product of any counting number & that whole number. There are an infinite number of multiples of 9. A multiple is what we get when we multiply something. The multiples of 9 are:

9, 18, 27, 36, 45, 54, 45, 63, 72, 81, 90, & so on, going up by 9 each time forever.

9,18,27,36,45,54,63,72,81,90,99,104 the rest of the multiples would be 18, 27, 36... etc It mainly depends which multiple. The multiples of nine up to 90 are:

9, 18, 27, 36, 45, 54, 63, 72, 81, 90

sine table

Let us learn about sine table

The formulae for finding angle & sides of triangle can be easily remembered using the sentence - "Old Harry & His Old Aunt".

Sin (q) = Old/Harry = Opposite/Hypotenuse
Cos (q) = and/His = Adjacent/Hypotenuse
Tan (q) = Old/Aunt = Opposite/Adjacent

The sine function “sin x” is one of the basic functions encountered in trigonometry

The sine table is a function of an angle & is 1 of the most common of the 6 trigonometric functions. The sine function takes an angle & tells the length of the y-component of that triangle.

calculus tutoring

Let us learn about calculus tutoring

The nice thing about calculus tutoring is that your Calculus Tutor is easy to get, because all that is required is a good computer & an internet connection. Calculus Tutoring is in high demand across the country. Calculus is a notoriously difficult subject for many students in certain majors must pass it in order to earn college degrees. If student possess a thorough understanding of calculus, are willing to assist others, & have a desire to earn money, why not become a calculus tutor?
Calculus Tutoring requires lots of idea of having to search endlessly to fill your Tutoring roster may seem overwhelming. Tutors may feel so mentally exhausted trying to come up with ways to find students without spending a fortune that you may want to give up before you even get started.

transitive property

Let us learn about transitive property
The transitive property of equality states for any l numbers which are real number a, b, & c:
If a = b and b = c, then a = c.
The best example, 5 = 3 + 2. 3 + 2 = 1 + 4. So, 5 = 1 + 4.
a = 3. 3 = b. So, a = b.

Example 1: 6 = 4 + 2, 4 + 2 = 3 + 3 So, 6 = 3 + 3

Example 2: x = 3, 3 = y So, x = y

The transitive property of inequalities said that in case a number is less than or equal to a 2nd number, & the 2nd number is less than or equal to a 3rd number, then the 1st number is also less than or equal to the 3rd number

algebra test questions

Let us solve algebra problems which helps you to solve algebra test questions

Solve the expression: 4x + 1y + 13z + 6x - 6y +2z
4x + 1y + 13z + 6x - 6y +2z
Add the like terms
(4 + 6) x + (1 - 6) y + (13 + 2)z
Simplify the expression
10 x - 5y + 15z
So, the solution is 10 x - 5y + 15z.
Simplify the equation: 8a + 15 = 5a – 3
8a + 15 = 5a – 3
Subtract 15 on both sides of the equation
8a + 15 - 15 = 5a – 3 – 15
8a = 5a – 18
Subtract 5a on both sides of the equation
8a – 5a = 5a – 18 – 5a
3a = -18
Divide by 3 both sides of the equation = 3a/3 = -18/3
a = -6.
So, the simplified solution is -6.
