Uncertainty Calculator vs Aifer Learning App

Uncertainty Calculator evaluates the error propagation throughout the mathematical expressions comprised of variables of uncertain value. The application allows input of up to three value-error pairs (A, B and C), that can be used as a parameters in the final expression. Error values should be provided in absolute (100 +/- 5) or in relative format, the latter should appear in percent format (100 +/- 5%). The evaluated expression can include numerous functions, that provided by row of the appropriate buttons. Components and functions can be added directly to the expression field by pressing the corresponding buttons. To encompass expression into the preset formula, select the expression and press the corresponding formula button. Particular attention should be paid to placing brackets to avoid equation ambiguity. The application deals with independent, random errors. So if this is a case never use A + A, but rather 2*A and never A*A*A but rather A^3! Obviously, different parameters can be combined in any way (A+B or C *A^2 .. is perfectly fine). Angles for trigonometric functions can be provided in degrees or radians, and that should be reflected by setting a yellow button to "DEG" or "RAD". Bear in mind the importance of units in any of calculations! Implementation Examples: 1.The charge passing through an electrical circuit is defined by: Q = I * t, where I is the current and t is the time. Calculate the total charge value when a current of 0.15 ± 0.01 A passes through the circuit for 120 ± 1 s: Input: A = 0.15 ± 0.01, B = 120 ± 1 The final expression will be A*B, and press Calculate: The final value will be: 18 ± 1.2 Thus, it can be reported the total charge as 18 C ± 1 C. Important! One should only report as many significant figures as are consistent with estimated error! So the value should be rounded to the rightmost decimal place at which error applies. 2. A ball is tossed straight up into the air with initial speed vo = (4.0± 0.2) m/s. After a time t = (0.60 ± 10%) s, the height of the ball is h = vo*t - 0.5gt^2 = 0.636 m (g = 9.80 m/s^2). What is the value and uncertainty of height? Input: A = vo = 4.0 ± 0.2, and B = t = 0.60 ± 10%, then the final expression should be: A*B – 0.5*9.8*B^2 The final value will be: 0.6 ± 0.4 (meters).

Aifer is an online Learning Application. Aifer offers the best online coaching for UGC NTA NET, CUET UG, CUET PG, CSIR NET, M. Phil Entrance Coaching, TISS NET, and much more. Aifer Education is passionately committed to the advancement of Education, Exploration of wider key skills by providing smart classes and better guidance for our students. Along with the traditional methods such as academic timetable, classes by best faculties, recorded files of all classes, frequent mock tests, Aifer takes you to the heights of a rich learning experience that satisfy your quest for learning and achieving your dream career. • Unique modes of course: Live, liveline, selfline - three different modes of course is one of our unique and prime features. As we are committed to provide the best service to each student, our three modes of course will help students to choose according to their capability, time and availability. This is really favorable to students from different backgrounds who are preparing for competitive exams such as UGC NET Exam, CSIR NET exam, and MPhil Clinical Psychology Entrance Examinations. • Emotech experience of learning; the word Emotech denotes how we consider the emotional needs and wants of our students and aid them with highly advanced technology and learning tools. Along with professional live and recorded classes, we offer our every student an all-new better atmosphere by blending emotional and technological sides of learning. • Personalized mentoring: at Aifer, you are individually mentored by our qualified faculty who will be there for you right away. A personal mentor is someone who gives you personal attention and assistance. You can utilize them for individual conversations regarding your studies. • Progress tracking system: mock tests are a common thing in coaching institutes. Life puts more effort into making sure that you are improving with aifer’s coaching. Through the progress tracking system, We conduct tests to examine, evaluate and analyze your progress after joining Aifer. Further assistance is provided to each student according to the improvement. • Special focus on weak areas: primary motive behind the progress tracking system is to provide a special focus on weak areas of each student. If any of our students need individual attention in any topic of their subject, Aifer provides them necessary assistance. • Happiness project: Aifer believes in quality over quantity. Along with good results in the end, we want our students to be happy and content throughout the course with the services of Aifer. Through the happiness project, our faculty will ensure each student is having a cheerful learning experience together with excellent academics. • Do or Die: Do or Die, group, another exclusive feature of Aifer is meant for the ones who need a strictly scheduled and completely engrossed study mode. Compulsory activities like assignments on topics with deadlines will be given to group members and all activities will be comprehensively monitored by our faculties. If you are someone who desires to work hard and make sure it's in the bag, you can opt to join the Do or Die team. • Study Club: Different candidates may have different study mechanisms and time. Study clubs in Aifer are formed considering the need of students to have a classroom-like team whose subject and time of study are simultaneous. This feature of Aifer helps you to do combined study and discussions using online platforms including zoom.
