																	Inverse of a 3x3 matrix. 
																	Matrices when multiplied by its inverse will give a resultant identity matrix. 
																	Similarly since there is no division operator for matrices you need to multiply by the inverse matrix. 
																	Port 1 input matrix 3 by 3 matrix. 
															
													
									
	
		
	
																	In the past the term for adjugate used to be adjoint. 
																	In the below inverse matrix calculator enter the values for matrix a and click calculate and calculator will provide you the adjoint adj a determinant a and inverse of a 3x3 matrix. 
																	The name has changed to avoid ambiguity with a different defintition of the term adjoint. 
																	Calculating the inverse of a 3x3 matrix by hand is a tedious job but worth reviewing. 
															
													
									
	
		
	
																	The adjugate of a is the transpose of the cofactor matrix c of a. 
																	To find the inverse of a 3 by 3 matrix is a little critical job but can be evaluated by following few steps.
