this week i learnt the linear equations and some ways to do it , the ways are Solving using substitution and the Solving using elimination, and i know which equations i should use which way . I think this unit is a little easy and it is just need to pay attention to the details , i think the equations will be done ,.
this week i learnt that the form of the ax2+bx+cchange that ,we can get a new maths form And the product is positive then the two integers must be either both positive or both negative if the product is nagative the one integer is positive and the other is nagative
this week i learnt that what is founction and ehat is relation ,and also learnt that how can we do to know how to use them and to do that like f(a)= .so we can get the number
this week i have leant some easy questions and we can do it very easily i think it just a little difficult of the medel of every questions so that i need pay more attentions to the medel but the others it is not very difficult
this week i have learn that how to do some maths questoins likw X+AX+N and also find some ways to do thatand i also know that which way i need to do and i also know that how to make a medel to help us to deal with the questions like to get the same thing can also to help us to finish the questions
this unit l have learnt three kinds of ways to get the number of the trigonometry they are the tan sin cos and the meaning of them and l also learnt how to use them SOH CAH TOA so we can use them follow this rules and if we meet some questions that don t have the trigonometry we need to add a line to help us to finish the questions it is very useful
this week s math let me to learn the exponents .l think lt is a little difficult for me and l have learnt the knowledgen of how to answer the questions of that .l also learnt what l should notice and where maybe l will make mistake .also knowhow to do some difficult math problems and the problenmswith number over numbers.
