Question

if sinΦsecΦ= -1 and Φ lies in the second quadrant, find sinΦ and cosecΦ​

Answer 1

Answer:

Φ = 135 degrees

hope u can solve the rest

Step-by-step explanation:

sinΦ*secΦ=-1

sinΦ/cosΦ=-1

tanΦ=-1

Φ= 135 degrees ( since Φ lies in second quadrant)

Answer 2

Step-by-step explanation:

$\sin( \alpha ) \sec( \alpha ) = - 1 = > \tan( \alpha ) = - 1$

$= > \alpha = \frac{3\pi}{4}$

$\sin( \alpha ) = \sin( \frac{3\pi}{4} ) = \frac{ - 1}{ \sqrt{2} }$

And

$\csc( \alpha ) = \csc( \frac{3\pi}{4}) = - \sqrt{2}$

Hope it helps you.
