Find the Exact Value csc (210) csc(210) csc ( 210) 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. −csc(30) - csc ( 30) The exact value of csc(30) csc ( 30) is 2 2. −1⋅2 - 1 ⋅ 2.

Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2. WebJun 25, 2016 · Noah G.

WebOct 21, 2015 · #arcsin(x) = sin^-1(x)# is the inverse function of the function #sin(x)# That is: If #x in (-pi/2, pi/2)#, then #arcsin(sin(x)) = x#. If #x in [-1, 1]# then #sin(arcsin(x)) = x#. On the other hand: #csc(x) = (sin(x))^(-1) = 1/sin(x)# is the reciprocal of the #sin# function. I think some of the blame for this confusion has to lie with the common convention of … The three main functions in trigonometry are Sine, Cosine and Tangent.
