Question

sin(π−theta)÷cos(3π/2−theta)+tan(−theta)÷cot(π/2+theta)+sec(π−theta)÷cosec(π/2−theta)=1​​​

Answer 1

Answer:

Check if

cos(2π−θ).sin(π+θ).tan(2π−θ)

cot(

2

π

+θ).sin(−θ).(cotπ−θ)

=−cscθ

Answer

Open in answr app

cos(2π−θ).sin(π+θ).tan(2π−θ)

cot(

π

+θ)).sin(−θ).(cotπ−θ)

=−cosecθ

(cosθ)(−sinθ)(−tanθ)

(−tanθ)(−sinθ)(−cotθ)

=−cosecθ
