Since sin 90 is equal to 1, obtaining the reciprocal of 1 should yield csc (pi/2). csc (θ) = 1/sin (θ) sec (θ) = 1/cos (θ) cot (θ) = 1/tan (θ) And we also have: cot (θ) = cos (θ)/sin (θ) Pythagoras Theorem For the next trigonometric identities we start with Pythagoras Theorem: Dividing through by c2 gives a2 c2 + b2 c2 = c2 c2 This can be simplified to: ( a c )2 + ( b c )2 = 1 Now, a/c is Opposite / Hypotenuse, which is sin (θ). Free trigonometric equation calculator - solve trigonometric equations step-by-step. We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ pi/2 radians = pi/2 × (180°/pi) = 90° or 90 degrees ∴ csc pi/2 = cosec π/2 = csc (90°) = 1 Explanation:. csc( π 3) csc ( π 3) The exact value of csc(π 3) csc ( π 3) is 2 √3 2 3. When we see arccsc A, we interpret it as the angle whose cosecant is A. Rewrite csc(2π) csc ( 2 π) in terms of sines and cosines. Evaluate Trigonometric Functions. 1 sin(2π) 1 sin ( 2 π) Subtract full rotations of 2π 2 π until the angle is greater than or equal to 0 0 and less than 2π 2 π. and rises 2 ft 9 in. Cosec pi/6 can also be expressed using the equivalent of the given angle (pi/6) in degrees (30°). How to Find the Value of Cosec pi/3? The value of csc pi/3 can be calculated by constructing an angle of π/3 radians with the x-axis, and then finding the coordinates of the corresponding point (0. org Introducción a las derivadas parciales (artículo) / Khan Academy khanacademy. 3 Use the cosine and sine cofuntion identities to prove the cofunction identity tan(90 ∘ − x) = cot(x) Answer. x = arccsc(2) x = arccsc ( 2) Simplify the right side. We know that sin x is equal to for all integral multiples of pi, that is, sin x = 0 implies that that x = nπ, where n is an integer.
