I have the following instruction, "Use trigonometric identities to transform one side of the equation into the other" ?
First I don't exactly understand what the instructions are saying.
The problem is as follows
cos Θ sec Θ = 1
The book gives me the solution which is
cos Θ sec Θ = 1 = 1
( 0 < Θ < π/2) (I guess this means Θ is an acute angle)
