If sin(A)=cos(A) was is the angle measurement?

 

sin(A)=cos(A)cos(A)sin(A)=0sin(45A)=sin(45)cos(A)cos(45)sin(A)sin(45)=cos(45)=22sin(45A)=22cos(A)22sin(A)sin(45A)=22(cos(A)sin(A))22sin(45A)=022sin(45A)=cos(A)sin(A)sin(45A)=045A=arcsin(0)45A=0±n360nNA=45±n360sin(45A)=sin(180(45A))=0180(45A)=arcsin(0)18045+A=arcsin(0)135+A=0±n360nNA=135±n360A=135+360±n360A=225±n360
