Let us define acute angle

An acute angle is 1 which is less than 90° is know as acute angle

A triangle has angle 43º, 64º and 73º. What type of triangle is this?

Solution: Here all the given angles are less than 90°, hence the given triangle angles are an acute triangle.

A triangle has angle 39º, 65º and 76º. What type of triangle is this?

Solution: Here all the given angles are less than 90°, hence the given triangle angles are an acute triangle.

A triangle has angle 45º, 56º and 79º. What type of triangle is this?

Solution: Here all the given angles are less than 90°, hence the given triangle angles are an acute triangle.

weighted mean formula

Let us learn about weighted mean formula

-->

Weighted mean is referred as the same as that of arithmetic mean. Where as each of the data is contributed uniformly with the weighed value. Incase all the weighted values are equal, and then the weighed mean is equal to the arithmetic mean. Weighted mean generally behaves similar fashion to the arithmetic mean. The term weighted average can also be known as weighted arithmetic mean or weighted harmonic mean.

• First calculate the sum for allocated weighted value & observed value.
• Second calculate the sum for all the observed values.
• Third make the division for the above 2 calculated values.

sin 90 degrees

Let us learn about sin 90 degrees

sin90°, sinα = y/x, 90° angle is known as a right angle y =1 r= 1 x = 0

sin 90° = y/r = 1/1 = 1

By the meaning in trigonometry, sin x = opposite/hypotenuse

Where “x” indicates any degree. In this case the x is 90⁰ that are we need to get the value of sin ninety degrees. Hence we need to draw the right angled triangle.

· A right angled triangle opposite side’s length is equal to hypotenuse side length.

· the sine of the angle = The length of the opposite side is divided by Hypotenuse length

Finally sin 90⁰ = the length of the ‘hypotenuse side’ is divided by The length of the ‘hypotenuse side’

= 1.

· The normal outline of sin can be mention as sin X = cos(90-X), hence sin 90 = cos (90-90) = cos 0 =1

calculus 101

Let us solve problem on calculus 101

-->

Solved Integral Calculus 101 problems

Evaluate the integral of the mentioned equation 6x²+18x dx.

Solution:

∫6x²+18x dx = ∫6x² dx +∫18x dx

Integrate the above equation

We get,

-->6x³/3 + 18x²/2

2x³+ 9x². = 2x³+ 9x²

Integrating the following expression 2e^x + 13e^x .

Solution:

The given expression is 2e^x + 13e^x

= ∫ 2e^x+ 13 e^x dx

= ∫ 2 e^x dx + ∫ 13 e^x dx

= 2e^x+ 13 e^x + c. = 2e^x+ 13 e^x + c

derivative of inverse tangent

Let us solve problem on derivative of inverse tangent

-->Derivative of inverse tangent angle when z =sixty.

Angle = arctan z

Angle = arctan sixty

Angle = 1.554131203081 radian

In degree mode 89.045158746128

Derivative of inverse tangent angle when z=90.

Angle = arctan z

Angle = arctan ninety

Angle = 1.5596856728973 radian

In degree mode = 89.363406424037.

triangle solver

Let us learn about triangle solver

-->

Triangle Solver is referred as multi-platform compatible. Enter 3 out of the 6 variables & this will solve for the rest. Triangle Solver uses both the law of cosines & the law of sine to find the missing values.

Triangle solver refers to solve the triangle problem using standard geometry formula. Triangle is a 1 of the 2 dimensional object in geometry .Triangle was categorized more types based on the length of the triangle & angle of the triangle. Special type of triangle is right triangle applying trigonometry function for solving right angle triangle

Find the perimeter of equilateral triangle that side length is 12.5cm?
Solution: Perimeter of the equilateral triangle = three* side length (3a)
= 3*12.5 =37.5cm

smart tuition online

Let us learn about smart tuition online

-->With ever increasing class sizes, & the decreasing attention spans of student, it is no wonder that students are learning less from the classrooms. Pair this with the ever increasing standards of the local education system & this spells trouble. I believe that private tuition is another forum for learners to learn & have their questions answered, in face of some inadequacies of the current education system in place. smart tuition online is no longer a luxury, but a necessity to do well in today's competitive arena. smart tuition online is a fact that students need tuition in order to keep up with their peers and excel. A qualified private tutor will use a variety of tutoring methods to work through difficult areas of a subject so that the core concepts remain long after the session is finished. In this way the children can, more often than not, recall facts & figures during tests, quizzes & exams & this can only lead to better marks
Therefore smart tuition online believe in providing quality tutors that will help your children excel & compete with his/her peers. Here at smart tuition online, our tutors are dedicated and committed in providing the best for your students. Smart tuition online agencies play an important part in the education process. Smart tuition online is a wise investment in a child's future. Any parents, who have the means, would want the best tutor or train to help build a solid foundation for their children's future career!

When many of us turn towards smart tuition online for help, where teachers are more motivated, both due to the fact that you’re paying them directly, & also if it is home tuition, full attention will be given to student & student’s work. No favoritism, ostracism of any sort, & as someone who had given private tuition, the success of students will only add to your own satisfaction.
