suppose that is an angle in standard position whose terminal side intersects the unit circle at -4/5 -3/4

Question

Find the exact value for sec tan sin

Answer 1

Hi Rari A.,

The point (-4/5, -3/4) is not on the unit circle, √[(-4/5)² + (-3/4)²] = √[481]/20 = 1.1 ≠ 1².

If your point is actually (-4/5, -3/5) which is on the unit circle, √[(-4/5)² + (-3/5)²] = 1.

That would put the terminal side in quadrant III. But since this forms a 3,4,5 right triangle off of the negative x-axis, the angle cannot be exact.

Conclusion, there is no correct answer with the information given.

I hope this helps, Joe.
