Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosecant is negative in the third quadrant. The exact value of csc(90) csc (90) is 1 1. Multiply −1 - 1 by 1 1.

Oct 12, 2021 · Question 1: What is the exact value of sin 270? Solution: Here sin is positive only in 1st and 2nd Quadrant. 270° does not lies in 1st and 2nd Quadrant. therefore sin (360° – θ) = – sin θ. sin (270°) = sin (360° – 90°) sin (270°) = – sin (90°) sin (270°) = – 1 . …

Feb 9, 2019 · In this video, we will learn to find the value of cosecant of 270 degree. Following is the URL of video explaining “How to find the value of sin(270)?”https:...

Calculate csc(270) csc is found using Hypotenuse/Opposite. Determine quadrant: Since 180 270 270 degrees it is located in Quadrant III. tan is positive. Determine angle type: 270 > 90°, so it is obtuse. Simplify Formula

What is the value of csc (270) ?

To obtain 270 degrees in radian multiply 270° by π / 180° = 3/2 π. Csc 270degrees = csc (3/2 × π). Our results of csc270° have been rounded to five decimal places. If you want cosecant 270° with higher accuracy, then use the calculator below; our tool displays ten decimal places.

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosecant is negative in the third quadrant. The exact value of csc(90) csc (90) is 1 1. Multiply −1 - 1 by 1 1.

Mar 7, 2025 · Cosecant is the reciprocal of sine: \csc \theta = \frac{1}{\sin \theta} Cotangent is the reciprocal of tangent: ... The secant function is undefined where cosine equals zero. Therefore, its domain excludes angles like 90^\circ and 270^\circ . Range of Secant Function: Secant values can range from (-\infty, -1] \cup [1, \infty) .
