Question

evaluate : (cosec square 45 degree + sin 30 degree )(tan 45 degree + sec square 45 degree) / sin square 60 degree cos square 45 degree

Answer 1

(cosec square 45 degree + sin 30 degree )(tan 45 degree + sec square 45 degree) / sin square 60 degree cos square 45 degree = (2 +1/2)(1+2)/(3/4*1/2)=(5/2*3)/(3/8)=15/2*8/3=5*4=20answer
