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

Answer:
x = 10.58
Step-by-step explanation:
It seems the equation is following
3 and 2 will simpy multiply and become 6
will go to RHS and will multiply with 19
6(x+6) will become = 6x + 36
6x = 42.48 + 21
6x = 63.48
x = 10.58
