Find the general values of `theta` from the following equations:
i) `sin3theta=cos3theta`
ii) `2cos^(2)theta=1-2sinthetacostheta`
iii) `"cosec"^(2)theta+2"cosec"theta-3=0`

Text Solution

Verified by Experts

i) `theta=1/3(npi+pi/4)`, ii) `theta=1/2(npi-pi/4)`
iii) `theta=npi+(-1)^(n)pi/2, theta=npi+(-1)^(n), alpha` where `sinalpha=-1/3`
