WebTrigonometry. Evaluate csc (390 degrees ) csc(390°) csc ( 390 °) Remove full rotations of 360 360 ° until the angle is between 0 0 ° and 360 360 °. csc(30) csc ( 30) The exact value of csc(30) csc ( 30) is 2 2. WebThe angle 390°, coterminal to angle 30°, is located in the First Quadrant (Quadrant I). Since sine function is positive in the 1st quadrant, thus sin 390 degrees value = 1/2 or 0.5. Similarly, sin 390° can also be written as, sin 390 degrees = (390° + n × 360°), n ∈ Z. ⇒ sin 390° = sin 750° = sin 1110°, and so on.

WebFind the exact value of cot(390 degrees) Thanks! .. The problem here is to determine the reference angle. Using the unit circle to illustrate this, starting from zero deg, rotate counter-clockwise 360 deg or 2pi radians plus an additional 30 deg, which is the reference angle. The cot of that angle, 30 deg, is the adjacent side/opposite side ... WebThe angle 390°, coterminal to angle 30°, is located in the First Quadrant (Quadrant I). Since secant function is positive in the 1st quadrant, thus sec 390 degrees value = 2/√3 or … greenhithe library

WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. WebOct 18, 2015 · Explanation: cscx = 1 sinx. If you try to calculate this for angle 0 you will get an expression with dividing by zero which cannot be calculated, so you cannot calculate cosecans of an angle which is a solution of sinx = 0, so the cosecans function is undefined for any angle from the set: x = kπ for any k ∈ Z.
