I don't understand thick head method in his third line how come icosa+jsina..... how cos and sin come
Ok thx
Linear function is straight function and other examples ???
Can anyone give me functions examples In real world. ...
I need circle explaination
That's I undersand but how cos and sin come in circle that true that it make angle alpha n beta but in angle a with x axis clock wise how this come icosa+jsina??
sin = opp/hyp what is opp i konw only base altitude hypotenus
But i dont know vectors so how i find perpendicular and also dont know this perpendicular question first i want know what is this .. thats not only question but also theory question what i do with ans this also in my keybook but in exams mcqs and also conceptual question so what i do in exam
Can u plz tell me concept of dot and cross product
Now this one:
<3,1,5> x <8,4,3>
3-20,40-9,12-8
-17,31,4
How take cross product
I Want concept also.
What is x
21-24,20-14,12-15
-3,6,-3
How take cross product
No explaination of determinant rules
I read all topic of vectors but not understand what is this in this link
the cross product, a × b, returns a vector that is perpendicular to both a and b
How perpendicular what is methods of a.b and a×b etc plz tell
Ok show me methid
Can this proof become more simple??? WHERE this circle comes from
Question 2
Find a vector perpendicular to each of the vectors
A vector =2i+j+k
b vector =4i+2j-k
Hi I have vectors topic problems
My 1 st question is prove that vectorially cos (a+b)=cosacosb-sinasinb
A and b are alpha and beta respectively plese help and also tell by diagram every single step
Thx....
Thx it clearing me!!,, slowly slowly
