kicyunya [14]

Answer:

f(x) = + cosx or - cosx

Step-by-step explanation:

(2+tan^2x/sec^2x) -1 =(f(x))^2​

=(( 1 + sec^2x)/sec^2x) -1

= 1 / sec^2x + 1 - 1

=  1 / sec^2x

= cos^2x

(f(x))^2​ = cos^2x

f(x) = + cosx or - cosx

How would I translate this algebraic expression?
FromTheMoon [43]

Answer: \frac{5}{7} (2+\frac{6}{r} )

Step-by-step explanation:

Since, the quotient of 6 and r = \frac{6}{r}

The sum of two and the quotient of 6 and r

= (2+\frac{6}{r} )

And,  Five-sevenths of the sum of two and the quotient of 6 and r

= \frac{5}{7} (2+\frac{6}{r} )

Thus, the required expression is, \frac{5}{7} (2+\frac{6}{r} )
