Question

sin(-theta)tan(180+theta)tan(90+theta) /cot(90-theta)cos(360+theta)sin(180-theta)

Answer 1

Answer:

cosec(@)

Step-by-step explanation:

As,

theta =@

sin(-@).tan(180+@).tan(90+@)/cot(90-@).cos(360+@).sin(180-@)

(we know sin,cos,tan,cot,sec,cosec change in 90 and 270

but not change in 180 and 360

sin to cos,tan to cot,sec to cosec)and sign according to quadrant rule

so,

[email protected]@.-cot@/[email protected]@.sin@

cancel sin@ and tan @

we get,

+cot@/cos@,(cot@=cos/sin@),cancel cos@

1/sin@,

cosec@(ans)
