Step-by-step explanation:
Given voltage of primary coil is
And voltage of secondary coil is
A transformer is a device that contains primary and secondary coil. These coils are mounted on soft iron. The change in voltage depends upon the number of turns of primary coil and secondary coil
.
Following equation represents the relation between them.
Then, ratio of the number of wire turns on the primary coil to the number of turns on the secondary coil is
Answer:

Step-by-step explanation:
Using the trigonometric identities
secx = , cosecx =
cotx = , tanx =
Consider the left side
secA cosecA - cotA
= ×
-
= -
=
= ( cancel sinA on numerator/ denominator )
=
= tanA = right side ⇒ proven
