QuickMath will automatically answer the most common problems in algebra, equations and calculus faced by high-school and college students.
Now this is now a series, as we have added together the n terms of a sequence. Some problems may have more than one correct answer. You can usually find the exact answer or, if necessary, a numerical answer to almost any accuracy you require. You can also plot inequalities in two variables.
In such cases, grid only one answer. The matrices section contains commands for the arithmetic manipulation of matrices.
The inequalities section lets you solve an inequality or a system of inequalities for a single variable. They each start with a particular first term, and Algebra questions and answers to get successive terms we just add a fixed value to the previous term.
We can use algebraic notation to represent an arithmetic progression. For questionssolve the problem and enter your answer in the grid on the answer sheet. Please refer to the directions before question 16 on how to enter your answers in the grid.
This is an arithmetic series, and we can find its sum by using a trick. But on the right-hand side, we are going to add the terms in the two series so that each term in the first series will be added to the term vertically below it in the second series.
No question has a negative answer. Figures provided in this test are drawn to scale unless otherwise indicated. We could also subtract a constant instead, because that is just the same as adding a negative constant. Any sequence with this property is called an arithmetic progression, or AP for short.
If you obtain a decimal answer with more digits than the grid can accommodate, it may be either rounded or truncated, but it must fill the entire grid. The numbers section has a percentages command for explaining the most common types of percentage problems and a section for dealing with scientific notation.
You will receive credit only if the circles are filled in correctly. For student-produced response questions, students will also see the following directions: For questionssolve the problem and enter your answer in the grid, as described below, on the answer sheet. So the difference between consecutive terms in each sequence is a constant.
All variables and expressions used represent real numbers unless otherwise indicated. Turn to Section 3 of your answer sheet to answer the questions in this section.
What would we get if we wanted to add the first n terms of an arithmetic progression? The graphs section contains commands for plotting equations and inequalities. Mark no more than one circle in any column.
Send What can QuickMath do? The equations section lets you solve an equation or system of equations. The algebra section allows you to expand, factor or simplify virtually any expression you choose. Introduction The directions and question numbers below are representative of what students will encounter on test day.
All figures lie in a plane unless otherwise indicated. We are now going to add these two series together. Some math sections allow the use of a calculator, while others do not, as indicated in the directions.
In the first sequence we add 2 to get the next term, and in the second sequence we add We shall let a stand for the first term of the sequence, and let d stand for the common difference between successive terms.
It also has commands for splitting fractions into partial fractions, combining several fractions into one and cancelling common factors within a fraction. The calculus section will carry out differentiation as well as definite and indefinite integration.
Let us write the series down again, but this time we shall write it down with the terms in reverse order. Although not required, it is suggested that you write your answer in the boxes at the top of the columns to help you fill in the circles accurately.Answer the 30 questions below and then click the button at the bottom of the page to immediately check your answers.
