Question

tan(-theta)/sin(540+theta)=?

Answer 1

Are you working in radians or degrees?

Answer 2

degrees,,,,,this question needs to be solved using the formula sin n pi=0

Answer 3

hmm. I was deceived by its looks. I don't think I can help. Sorry.

Answer 4

the answer i got is -sin^2 theta/cos theta, but the answer given in the book is sec theta... please verify

Answer 5

Though playing with sin(n*pi) on my calculator shows that it only holds when working in radians...

Answer 6

try solving on paper...using the formula i gave u.....it will be solved in 2 minutes....i just need the final answer....

Answer 7

someone please solve this question....got to work it for the test tommorow and also this one : [sin(90-theta)sec(180-theta)sin(-theta)]/[sin(180+theta)cot(360-theta)cosec(90-theta)]
