Solve the following equation: (i)tan3xtanx = 1 (ii)tan2x = -cot(x + pie/3) Share with your friends Share 6 Anuradha Sharma answered this 1) tan3x.tanx =1 So tan 3x = 1tan x=cot x or tan 3x = tanπ2-x or 3x = nπ+π2-x or 4x = nπ+π2or x = nπ4+π8 2) tan 2x = -cot x+π3 tan 2x = tanπ2+x+π3or tan 2x = tanx+5π6or 2x = nπ+x+5π6or x =nπ+ 5π6 1 View Full Answer
