WebOct 19, 2024 · cos theta = 3/5, theta in quadrant IV WebJun 9, 2016 · Since theta is in QII and equal to -4/7, find sine of theta by using the Pythagorean Theorem. x^2 + y^2 = r^2, where x = -4 and r = 7. (-4)^2 + y^2 = (7)^2 16 + y^2 = 49 y^2 = 49 - 16 = 33 y = ±√33. Because theta is in QII, y = +√33. sin (theta) = y/r = √33/7. To solve for csc (theta) realize that csc (theta) = 1/sin (theta). WebMay 22, 2015 · As required, set A = θ 2 & cos θ = 3 5 thus we get. sin θ 2 = ± 1 − cos θ 2 sin θ 2 = ± 1 − 3 5 2 = ± 1 5. Now, as per given constraints of θ. 360 o < θ < 450 o 180 o < θ 2 < 225 o. Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle θ 2 lies in the III-quadrant where ... boarding class
