1. Using the half-angle formulas fine the EXACT value of cos(22.5o) 2. verify the identity cos(3x)=(1-4sin2(x))cos(x) 3. find the EXACT solutions in the interval [0,2pi) sin(2beta)-2cos(beta)=0 ******Please do not use and decimals in the set or answer process***** Thank you so much
Verify that the equation is an identity. sec x-cos x =sin x tan x To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step. sec x-Cos x= -COS X = Use a common denominator to perform the subtraction = Separate the expression into two factors = sin x tan x
