To find:
The input if the output is 32.
The output if the input is 4.
Solution:
Input is x and output is c.
Substitute c = 32 in f(x).
Divide by 4 on both sides, we get
Taking cube root on both sides.
The input is 2 if the output is 32.
Substitute x = 4 in f(x).
The output is 256 if the input is 4.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• cot x =
• sec x = and cosec x =
Consider the left side
= × cosx
=
=
= -
= cosec x - sin x
= right side ⇒ verified
