    Structure in English

    I am not sure what PTELA anyhow. You can use PEEL or IDEAS. For PEEL in English stands for: - Point - Example - Explanation - Link Without the example first there will be no explanation. In this case example is some reference to quote with which you refer to some literacy technique like...

    SDD(software design and development) help needed

    I am not sure what your background is? But maybe stackoverflow coud help. Just the appropiate tags so something like <error message> [vba]. You might be able find some resources on vba online like Udemy, youtube or Code Academy. I feel like I have seen some similar post before?

    Intersection between 2 lines

    @HeeeHeee unfortunately I could not understand your question sin^-1 needs an argument you have not specified that. As result It is not clear what your are writing as a result sin^-1(x) is curve not a line. There is no guarantee there is close form solution mx + b = sin^-1(x) Edit try solvng...

    Graphs of cos^-1(cosx), cos(cos^-1(x)) , sin^-1(sinx) and sin(sin^-1(x))

    cos(cos^-1(x)), sin(sin^-1(x)) should be easy. Use the theorem f(f^-1(x)) = x. sin^-1(sinx), cos^-1(cosx) you need to examine by inspection to sketch and get the pattern. Use the theorem f^-1(f(x)) = x but this only holds for the domain of the sin^-1 / cos^-1 As an excerise try to prove the...

    Can I get some help with questions?

    I had another look at the question. I was not unfortunately able to understand the other answers. Theorem: if A and B are independent then P(B|A') = P(B) # This is actually converse of what we are looking to prove. Anyhow. Proof: P(A)*P(B|A) + P(A')*P(B|A') = P(B) Let P(A) = p, let P(B) =...

    Year 7 History Test Sample: Ancient Past and Ancient Rome

    I am not to sure how you can prepare as the syllabus seems vague. https://educationstandards.nsw.edu.au/wps/portal/nesa/k-10/learning-areas/hsie/history-k-10/content/1088 Maybe what you could do is try make your own essay questions and try to answer them. Look at the HSC papers to get an idea...

    Can I get some help with questions?

    I think often inspection is the way to go. So maybe number of ones from 101-200 201-300 . . 801-900 You will need to consider separately 901-1000 1001-1100 1101-1150

    perms and combs

    Assume cards of same character but different suit are different. That is club A, is different hearts A How many combinations are there of 5 cards with characters A, K, J? How many permutations are there of 5 cards with characters A, K, J?

    perms and combs

    When you want combination you need to divide by number of positions. When you want permutation that is the number of arrangements you don't want to divide. n-number of objects r- number of objects selected nPr is generally used for permutation. nCr is generally used for combinations but can...

    perms and combs

    When dealing with groups you are not going to care about order only what members a group consist of. In the case of equal size group: Let you say have a set of members L in group 1. and a set members K in group 2. It is also possible to have L in group 2 and K in group 1. Hence you divide...

    can some1 quick recap me on how to do such qs

    So if you have y = sin^-1(x) + cos^-1(x) Then dy/dx = 0. So you have a differential equation that you can solve. Another alternative would be draw triangles. So draw triangle with hypotenuse 1 and opposite side x for sin^-1(x) and hypotenuse 1 and adjacent side x for cos^-1(x). You will see...

    I never heard of sin^-1 being defined for complex numbers. Cool

    can some1 quick recap me on how to do such qs

    If the derivative is zero this means the function is constant. So once you plug in some point that is in the domain you will get the answer.
