Question

prove that !

Only brilliant students can give the ans.....

sec ( 90 - theta ) * cosec (90 - theta ) = sec^2 theta * cot theta

Answer 1

this is not a tough question.even a primary class student can answer this.

ans:

sec ∅ * cosec ∅ =  sec²∅ * cosec ∅/sec ∅

sec ∅ * cosec ∅ = sec ∅ * cosec ∅

hence proved

Answer 2

mark it as a brainielist
