How to determine angle quadrant
How to determine angle quadrant-May 05, 21 · Determine the quadrants 0 to π/2 first quadrant, so reference angle = angle, π/2 to π second quadrant, so reference angle = π angle, π to 3π/2 third quadrant, so reference angle = angle π, 3π/2 to 2π fourth quadrant, so reference angle = 2π angle 10π/9 is a bit more than π, so it lies in the third quadrantOct 21, 18 · if sinx=7/5 and angle x is in quadrant 2 and cos y=12/13 and angle y is in quadrant 1 find sin (xy) asked Nov 26, 13 in TRIGONOMETRY by harvy0496 Apprentice doubleangle;

If Tan 8 Is Positive And Sin 8 Is Negative In Which Quadrant Does 8 Lie Quora
Sal first finds the direction angle of a vector in the first quadrant, then moves onto a trickier one in the second quadrant to solve a for theta we could just say that theta is equal to the inverse tangent sometimes people say arctangent of 4/3 of 4 over 4 over 3 and let's evaluate this and I'm going to get my calculator out to do it so IThen $\tan^{1}\left({4\over3}\right) \approx 53^\circ$, which is in quadrant I However, this does not line up with our intuition of where this vector should land Hence, we may add $180^\circ$ to this degree measure to give us the correct angle measure which will land in quadrant III, since $53^\circ 180^\circ = 233^\circ$Namaste to all Friends, This Video Lecture Series presented By VEDAM Institute of Mathematics is Useful to all student
