tan19pie/3 can be written as tan{6pie-pie/3} then by solving this you get - \sqrt{x} 3
Cot(-15pie/4)= -cot(15pie/4)= -cot(3pie+3pie/4) = 1

Tan \frac{19\pi }{3} = Tan1140
                                                  = Tan 3*360 +60
                                                  = tan 60
                                                  = √3
Cot \frac{-15\pi}{4} = Cot -675
                                                                  = -Cot 2*360-45
                                                                  = -cot45
                                                                  = -1 

gursangatpreet: This question can solved without putting the value of pie?
MADHANSCTS: π = 180
gursangatpreet: Thanks
