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.

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

2021年10月12日 · 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 . …

2019年2月9日 · 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:...

What is the value of csc (270) ?

Find the value using the definition of cosecant. Substitute the values into the definition. Divide 1 1 by −1 - 1. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

Find value of csc(270) or Cosec(270) - Cosecant or Calculate value of Sin, Cos, Tan, Cot, Cosec, Sec, SinH, CosH, TanH, CotH, CosecH, SecH, ASin, ACos, ATan, ACot, ACosec, ASec and other trigonometry function

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.
