One answer is x>=0 (x is greater than or equal to 0). The best way to enter this in WeBWorK is by using interval notation: [0,infinity). Other intervals: (2,3] is the set .

Jan 5, 2022 · Mathematical Functions Available In WeBWorK. Unless otherwise specified, all of the functions listed below are enabled by default. However, sometimes one or more of these functions is disabled for a particular WeBWorK problem because the instructor wants you to calculate the answer by some means other than just using the function.

Jan 28, 2025 · This article will guide you through the steps of typing cube roots in WebWork, empowering you to input these expressions accurately and seamlessly. Understanding the precise syntax for inputting cube roots in the WebWork platform can be essential for students working on mathematical assignments.

The way to enter this in WeBWorK is in interval notation: [0,infinity). Other intervals: (2,3] is the set 2<x<=3. (-infinity,5) is the set x<5. (-infinity, infinity) is the set of all real numbers. (2,3]U[4,5) is the set 2<x<=3 or 4<=x<5. (This is a union of two intervals and can be very important.) Mathematical Constants Available In WeBWorK

Write sin(t) instead of sint or sin t. WeBWorK has been programmed to accept sin t or even sint to mean sin(t). But sin 2t is really sin(2)t, i.e. (sin(2))*t. Be careful. Be careful entering powers of trigonometric, and other, functions. You write (sin(t))^2 for the square of sin(t), and never sin^2t. 2 (4 x ) , 2+3sin^2(4x) is wrong.

How do I enter square roots or cube roots? For square roots, you can use sqrt() or the exponent 1/2. For example, the square root of two in WeBWorK is either sqrt(2) or 2^(1/2). For cube roots, use the exponent 1/3. The cube root of 7 is then 7^(1/3). Remember to put parentheses around fractional exponents: 7^(1/3) is not the same as 7^1/3.

Jan 15, 2025 · We will show you how to use the superscript symbol in Webwork, as well as provide HTML code that can be used for cube roots. With step-by-step instructions and practice exercises, you’ll gain confidence in accurately representing cube roots in …

x^ (1/3) gives the cube root of x. cos ( ): The Cosine function. Note: cos ( ) uses radian measure. sin ( ): The Sine function.

Jan 24, 2023 · Use the preview function to double check before you submit your answer, and use lots of parentheses. Nth roots are 1/n & you can use sqrt for square root.

Jan 26, 2018 · In the xyzhomework.com system (an implementation of the MyOpenMath homework system), we could ask students to input the “radical form” via either MathQuill (an online math expression editor) or by entering “root(n)(x)”.
