This channel was created to help students who are struggling in math. Currently, I have videos for Algebra, Liberal Arts Math, Trigonometry, and Statistics. More subject areas will be added in the future. I have over19 years of teaching experience at the high school and college level. If there are topics that you don't see that you need help in, please let me know. If any of the videos helped you, please consider subscribing and passing along the content to others you know that are struggling.
Your video is very helpful sis❤❤tomorrow is my exam and it is helpful ❤. can you tell me how to find range for it for example range for x^2-2x+1/x^2-x-6 And sorry for trouble sis😞❤.
There is another way of doing this with the n nspire cx2 that looks the same, but with hitting menu,6,3 then selecting sample or pop. I dont understand really whyh it coulld not be added into the calculation. When doing Var, and Std it seems like will likely be calculated at the same time and displayed with the mean.
I have a question: what if we are given a circle and it's not stated that there's a centre and also we r not given any radius . How do i work it out wen asked to write the equation of a circle
I have come across a book that provided an amazing shortcut for these questions. It suggested that we imagine creating a square with the given perimeter (2500 yd). Therefore, the side length of the square would be 625. Subsequently, we just need to calculate the area of this square, which is straightforwardly obtained by squaring 625, yielding the identical solution of 390625.
An empty set (aka null set) is a set that doesn't contain anything. For example, rolling a 7 on a standard six sided die is impossible to happen, so the set of numbers that match rolling a 7 would be a null set. You can either represent the null set as a circle with a line drawn through it or { }. If nothing matches the description, then it is null.
