Question

Sin70÷cos20+cosec20÷sec70-2cos70×cosec20=0

Answer 1

Hey buddy your answer is here....

Please see it

First L.H.S.

=sin70°÷cos20+cosec20°÷sec70°-2cos70°×cosec20°
=sin(90°-20°)÷cos20+cosec(90°-70°)÷sec70°-2cos(90°-20°)÷sin20°
=cos20°÷cos20+sec70°÷sec70°-2sn20°÷sin20°
=1+1-2
=0=R.H.S.
so
____________________________________
R.H.S.=L.H.S.
Hence proved.........
