If costheta equals frac2sqrt6 in Quadrant 1 then find tantheta?
tan theta = sqrt(2)/2 = 1/sqrt(2).
What is cosine 2 theta when sine theta equals .28?
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
What is csc theta when sin theta equals two-third with theta in quadrant one?
Your question is CscΘ=? when SinΘ=2/3 in Q1 well bases on the fundamental identities.. Sin Θ= 1/CscΘ and CscΘ= 1/SinΘ So when your in is 2/3 CscΘ=1/sinΘ CscΘ =1/(2/3) CscΘ = 3/2 -The value of cscΘ and it is positive because all functions in quadrant 1 are positive.. If you have more questions, please comment..:))
In which quardant are the terminal arms of the angle lie when sin thita is less then zero and cos thita is greater then zero?
The fourth Across the quadrants sin theta and cos theta vary: sin theta: + + - - cos theta: + - - + So for sin theta < 0, it's the third or fourth quadrant And for cos theta > 0 , it's the first or fourth quadrant. So for sin theta < 0 and cos theta > 0 it's the fourth quadrant
Can sine theta equals tan theta equals theta be equal for small angels?
Yes. (Theta in radians, and then approximately, not exactly.)
