(sin5theta+sin3theta)/(cos5theta+cos3the...

`(sin5theta+sin3theta)/(cos5theta+cos3theta)` is equal to

A

`sin 4theta`

B

`cos 4 theta`

C

`tan 4theta`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C

Now `(sin5theta+sin3theta)/(cos5theta+cos3theta)`
`=(2sin((5theta+3theta)/(2))cos((5theta-3theta)/(2)))/(2cos((5theta+3theta)/(2))cos((5theta-3theta)/(2)))`
`=(2sin4thetacostheta)/(2cos4thetacostheta)=tan4theta`
