**drwls**, Sunday, March 4, 2012 at 12:16amWhat is supposed to follow the 4cos^2_ ? If it is 4cos^2t, why can't it be added to the first term?

Are you supposed to solve for t or prove an identity?

Trig - Prove (cos^2t+4cos^2+4)/(cost+2)=2sect+1)/sect

Trig - Prove cos^2t+4cost+4/cost+2=2sect+1/sect

Trig - Prove cos^2t+4cost+4/cost+2=2sect+1/sect

Trig - Prove cos^2t+4cost+4/cost+2=2sect+1/sect

trig - Q1: Prove cos^2t+4cost+4/cost+2=2sect+1/sect Q2: A ship leaves port with ...

Math - Solving Trig Equations - What am I doing wrong? Equation: sin2x = 2cos2x ...

Trig - tan^2t/sect=sect-cost cott^2/csct=csct-sint

Math - Trig - Double Angles - Prove: cos4x = 8cos^4x - 8cos^2x + 1 My Attempt: ...

trig - cos@-4SIN@=1 then sin@+4cos@=

trig - Factor each expression: cos^2x- 2cosx+1 4cos^2x-1
