The transformation formula for coordinate systems is:
a) x=rcosθ
y=rsinθ
b) r2=x2 + y2  r=±x2 + y2
cosθ=xr, sinθ=yr, tanθ=xy
Calculation:
Convert formula to equivalent polar coordinates:
rcosθ= 1
Put x=rcosθ, y=rsinθ,
 x= 1
Hence the desired equivalent polar coordinates would be x= 1

Consider the linear system
y=[3264]y
a) Find the eigenvalues and eigenvectors for the coefficient matrix
λ11, v1=[12] and λ2=0, v2=[23]
b) For each eigenpair in the previos part, form a solution of y=Ay. Use t as the independent variable in your answers.
y1(t)=[] and y2(t)=[23]
c) Does the set of solutions you found form a fundamental set (i.e., linearly independent set) of solution? No, it is not a fundamental set.

Find linear transformation matrix from a linear transformation matrix of its composition
Let's say that V is a vector space over the field K and suppose we have a linear transformation f End V thats matrix is know on some basis.
How to find a matrix of a linear transformation g End V on the same basis, so that g g = f.
For example if V is vector space over the field Z 11 and matrix of linear transformation f End V on some basis is
( 7 ¯ 3 ¯ 4 ¯ 0 ¯ 0 ¯ 6 ¯ 9 ¯ 6 ¯ 1 ¯ 9 ¯ 3 ¯ 1 ¯ 0 ¯ 2 ¯ 8 ¯ 5 ¯ )

What is the transformation matrix?
In R 2 a basis is given a = ( a 1 , a 2 ) where:
a 1 = ( 1 , 1 )
a 2 = ( 0 , 1 )
For f : R 2 R 2 it is known:
f ( a 1 ) = 6 a 1
f ( a 2 ) = 1 a 2
Determine the matrix of transformation with regards to the standard e-basis.

Find a set of vectors that spans the plane P1:2x+3yz=0
asked 2022-01-10

Since 21+11+1+11+1+11+2 I thought i could do rn+1sn+1=1+11+1+11+1+11+rnsn with the following piece of code :

ite = 8
int r = 1;
int s = 1;
int R = 0;
for (int i=0,i<ite,1){
    R = 3*r+4*s;
    s=2*r+3*s;
    r=R
}
int result = r/s;
System.out.println(result);

But it's not exactly the code one would get using picard's iteration method, so my answer does not fit the criteria. What am-I doing wrong?

 

If one does not know the answer but knows how to visualise picard's method for calculating sqrt(2) on a graph that would already help me a lot.

 

Thanks in advance
