Apr 5, 2018 · cos(pi/2-x)*csc(-x)=-1 for x not a multiple of pi. We know that the angles of a right triangle must sum to pi radians. Since the right angle is pi/2 radians, the other two angles must sum to pi/2 radians. Therefore pi/2 minus the adjacent angle must be the opposite angle.

Question: Verify the identity. CSC(x) cos2(x) + sin(x) = csC(x) CSC(x) cos2(x) + sin(x) sin2x) sin(x) sin(x) 1 = Il Verify the identity. sec(t) – cos(t) = sin(t) sec(t) Use a Reciprocal Identity to rewrite the expression in terms of cosine only, and then simplify. 1 cos(t) sec(t) - cos(t) sec(t) 1 cos(t))(cos(t)) = 1 - ( Use a Pythagorean Identity.

If cscx=2,90∘<x<180∘, then sinx2= ; cosx2= ; tanx2= Here’s the best way to solve it. Solution.

We're trying to prove that #csc(-x)/sec(-x)=-cotx#. You'll need to use reciprocal identities: #secx=1/cosx# #cscx=1/sinx# and also angle difference formulae: #sin(x-y)=sinxcosy-cosxsiny# #cos(x-y)=cosxcosy+sinxsiny# Here's the actual problem. I'll be manipulating the right side of the equation until it equals the right: #LHS=csc(-x)/sec(-x)#

Oct 3, 2015 · S = {arcsin(1/4), pi - arcsin(1/4), (3pi)/2} Reewrite csc(x) as y y^2 = 3y + 4 Make one of the sides equal 0 y^2 - 3y - 4 = 0 Solve the quadratic either by sum and product, (wielding 4 and -1) or by the formula y = (3 +- sqrt(9 -4*1*(-4)))/2 = (3 +- sqrt(9 +16))/2 = (3 +- sqrt(25))/2 y= (3 +- 5)/2 r_1 = (3+5)/2 = 8/2 = 4 r_2 = (3-5)/2 = -2/2 = -1 So we know that csc(x) = 1/sin(x) = …
