inequalities calculator

Let us learn how to use inequalities calculator

Add all numbers in left side from the in equality.

Then add all numbers in right side from the inequality.

Add the entire variable with coefficients on the left side from inequality.

Add the entire variable with coefficients on the right side from the inequality.

Subtract all number on left side from both sides of the inequality.

Add all number on the left side from both sides of the inequality

Subtract all variable with a coefficient on the right hand side of the inequality from both sides of the inequality

Add all variable with a coefficient on the right hand side of the inequality from both sides of the inequality.

Simplify by dividing on both sides or by multiplying on both side with reciprocal of inequality.

sin 30 degrees

Let us learn about sin 30 degrees

Value of 30 Degree

• The value of sin 30 degrees = ½
• The value of cos 30 degrees =√3/2
• The value of tan 30 degree = 1/√3

zero degree angle is known as an acute angle, because the angle of 2 rays Is less than 90 degree & greater than 0 degree.

sin(135) = sqrt(2)/2
cos(135) = -sqrt(2)/2
sin(30) = 1/2
cos(30) = sqrt(3)/2

Note 135 deg is just the 45 deg angle in the upper left quadrant of the unit circle, where sines are postiive & cosines are negative

sin(135-30) = sin135cos30 - cos135sin30
................... = [sqrt(2)/2][sqrt(3)/2] - [-sqrt(2)/2][1/2]
.................. = sqrt(6)/4 + sqrt(2)/4
.................. = [sqrt(6) + sqrt(2)]/4
................... = 0.9659

sin(135) - cos(30) = sqrt(2)/2 - sqrt(3)/2
................................= [sqrt(2) - sqrt(3)]/2
................................= -0.1589

factoring calculator online

Let us solve problem using factoring calculator online

Factor the given expression, 2x² + 4x
Solution:
= 2x² + 4x
Taking the common terms outside,
= 2x(x + 2)
The solution is 2x (x+2).
Solve 6x² + 18x - 24 = 0 for x.
Solution
Given equation is 6x²+18x-24=0 for x.
Solve the given equation we get
. (6x - 24)(x + 1)=0
Here by equating the values to zero
6x-24=0, x+1=0
Here keep constant terms on 1 side & move the variables to other side.
6x=24, x=-1
The final solution is X=3/2, x = -1.

midpoint formula calculator

Let us learn about midpoint formula calculator

The midpoint formula calculator is very handy while calculating the midpoint between any 2 points & is very commonly used in geometry both practically & during learning. In math, midpoint formula questions are very common & Learner should be well aware of how to use the midpoint formula calculator. The formula to find midpoint using calculator is actually quite logical, if you try to look at it closely, you will find that it is derived from the average of the x coordinates & y coordinates

The midpoint formula calculator is used when you need the point that is exactly between 2 other points. The midpoint formula is used when you need to find a line which bisects a specific line segment. Essentially, the 'middle point' known as the "midpoint"

alphabet of lines

Let us learn about alphabet of lines

The "Alphabet of Lines" defined as the different styles of lines used in drafting such as to show different features about an object which is drawn, hidden, Construction, cutting-plane, visible object, dimension, phantom, center, extention, section, & border. Or alphabet of lines is a geometrical object that is straight, infinitely long & infinitely thin.

Drafting or Computer Aided Drafting: The alphabets of lines are the different line that architects, draftsmen, engineers, et al use when constructing a drawing. The Alphabet of lines is referred as the different types of lines. The use of line types on a drawing is used to describe the various features of an object to the person reading the print. Alphabets of lines help to illustrate & describe the shape of objects which will later become real parts.
The best example, a thick solid line is known an object line and represents the outline of a part on a drawing. A dash line represents an edge which is not visible in a particular view; therefore it is called a hidden line. Other common lines used in drafting include extension lines, dimension lines, construction lines, border lines, center lines, among many others depending on the type of drawing.
