tan225=tan(125+100),


tan(180+45)= (tan125+tan100)/(1-tan125tan100),


tan45=(tan125+tan100)/(1-tan125tan100),


1=(tan125+tan100)/(1-tan125tan100),


tan125+tan100=1-tan125tan100,


tan125+tan100+tan125tan100=1.

Solve for x: 4cos6x-sin6x=cos^3x+3cos2x
 
 
4cos6x-sin6x=cos^3x+3cos2x for x=0,. 4-0=1+3 means x=0 is a solution for x=pi 4- 0= -1 +3 , not a solution. hence only 2npi , is solution of the equation where n=1,2,3..............
