How do I prove:
1/sin@ csc@ -2sin@
________ + ______ = _____
1 + CSC@ 1-1/sin@ cos^@
I am trying to solve for A and B but haven't been able to find a trig identity that will help me.
1.414 = .5cosA + cosB
.5 = .5sinA - sinB
how do I solve this?
-------------------- = tan(3x)
1-sinQ 1 ---- = tanQ + --- 1+sinQ cosQ
my question is I need to solve this identity :
cos x csc x - sin x sec x = 2 cot 2x
Verify the identity: (1+cot2X)(1-cos2X)=2
Question: How do I solve this problem?
sin3x cos3x _____ - _____ = 2 sinx cosx
I've being having trouble with this one on my correspondance course.
