→ Substitute cos 2x and sin 2x by their expressions
→ Subtract both sides by sin x
→ Take sin x as a common factor in the right side
From the graph, the equation has 4 solutions, the intersection points between the 2 graphs
Answer:
no
Step-by-step explanation:
to know if it is a function or not look at the x coordinate if any of the x coordinates repeat then its not a function but of any of the x coordinates don't repeat than it is a function
Answer:
27 days
Step-by-step explanation:
It is a simple division question
18 / (2/3)
Multiply by reciprocal
18 * 3 / 2 = 27
Answer:
h(f(x)) = x
Step-by-step explanation:
Since the functions are inverses h(x) undoes f(x)
That is if f(x) = x then inverse function maps back to x
h(f(x)) = x
