Question

evaluate cos squared theta minus 8 by cos square theta​

Answer 1

($cos^{2}\theta$ - 8) ÷ $cos^{2}\theta$ = 1 - (8 ÷

Step-by-step explanation:

May be the question is incorrect , if the question is

($cos^{2}\theta$ - 8)  ÷

Apply the fraction ( a ± b ) ÷ c = ( a ÷ c ) ± ( b÷c )

                              ( a + b ) ÷ c = ( a ÷ c ) - ( b ÷ c )

                    ($cos^{2}\theta$ - 8 ) ÷

Apply the rule  (a ÷ a ) = 1 , then ($cos^{2}\theta$ ÷ $cos^{2}\theta$ ) = 1

($cos^{2}\theta$ - 8) ÷$cos^{2}\theta$ =  1 - ( 8 ÷ $cos^{2}\theta$)
