how to solve (5x1) matrix?

hello guys

i want to solve this matrix

___________________ _________

I sin30 , 0, 0 ,0 , 0 I I -0.937 I

I cos30 , -1 , 0 , 0 , 0 I I 0 I

I 0 , 0 , -sin 60 , 0 , 0 I I 3 I

I 0 , 0 , 0 , -sin30 , 0 I I -2.0625 I

I 0 , 0 , 0 , cos30 , -1 I I 0 I

___________________ _________

can someone please write the code sheet to solve this , i its it a plus matrix

NOTE : The I around reprsents the frame for when you write it in paper

thanks

I believe I can mimic the shortest answer I have seen on this forum:

To give this answer a bit more substance: you need to use the m function.

A=[sin(30),0,0,0,0 ; 2,-1,0,0,0 ; 0,0,3,0,0 ; 0,0,0,4,0 ; 0,0,0,5,-1];
b=[-1;0;0;-2;0];
A\b

ans = 5×1

1.0121 2.0242 0 -0.5000 -2.5000

Now you just need to put your arrays in the Matlab syntax I showed, run this code yourself and you will have a solution to this system.

Regarding your flag ("incomplete answer"):

@Blaine French, can you explain what is incomplete about this answer?

Remember to work with "sind" and "cosd" instead of "sin" and "cos" if the angle is in degrees and not in radians.
