Answer:
Step-by-step explanation:
we are given
we can simplify left side and make it equal to right side
we can use trig identity
now, we can plug values
now, we can simplify
now, we can factor it
we can use trig identity
we can cancel terms
now, we can simplify it further
now, we can use trig identity
we can replace it
so,
Answer:
and
Step-by-step explanation:
If we want to express as
, this means that put the function
into
of
to get
.
The function is given as
<u>So we need to figure out a function that we can put into another
to get
</u>
If we let and
, we can clearly see that putting g(x) into x of f(x) will give us
, which is y.
Hence and
